Make sure to properly nest \begin{lang} and \end{lang} tags even
when no language package is selected. In this case, LyX assumes
that babel is being used, so the language names might be wrong
if the user arranged for using polyglossia in the preamble.
Nevertheless, we assure that the produced output is syntactically
correct, so that by adding proper preamble code a correct output
is still possible.
As it was, the comparison buffer was sharing a DocumentClass with
the buffer from which the document settings are taken.

It seems that the internal Qt5 caching does not work well here,
especially in the case of ancient Hebrew documents.

When an inset wants to use the whole available width, it is necessary
to take into account that some of this width may already be taken by
the end-of-paragraph (pilcrow) marker.
Fixes bug #10537.

getPosNearX, which is the only user of x2pos, should always return the
nearest position.
In editXY, there is a need to return the position where the inset
stands, but it is done using checkInsetHit.

The code that looks whether neighbor block has a different direction
should look to the left or to the right depending on the direction of
the current block.
Fixes part of bug #10569
(cherry picked from commit e3d252cd62)
Instead of using complicated (and wrong) code, it is better to use
getPosNearX here.
Also simplify the code by removing temporary variables.
Fixes part of #10569.

With RtL text, the method can be non-monotonic wrt x value (which is a
Qt bug). To work around this, we check whether positions adjacent to
those returned by xToCursor look better. Depending on whether the new
x position is too small or too large, we look backward or forward for
a better solution.
The performance is probably not great, but this is only needed for
user interactions, so the performance penalty should not be a problem.
Fixes part of #10569.

This is a regression at b0673bd1. The code referred to row.pit(),
which was not correctly initialized in this case. The bug does not
exist in master, since the code in redoParagraph has been cleaned-up
and row.pit() is always correct.
Two corrective measures are taken, each of which would fix the bug:
- do not use row.pit() in breakRow, but directly the pit parameter.
- initialize row.pit() correctly in the faulty case.
When including files, LyX always searches the user and the system
directory, in that order. This means that when using local layout
files broken down into multiple includes, the various includes should
be specified with a path relative to the user layouts directory
(typically ~/.lyx/layouts), making this very impractical.
This commit allows including local files by specifying their path
as explicitly relative to the main layout file position, i.e., by
specifying their path with either "./" or "../". If the main layout
is not loaded from a local file, the usual search order is used,
even if the path are explicitly relative. So, for system layouts,
both "Input ./name.inc" and "Input name.inc" are equivalent.

Because latex allows to do so, and there is no easy way to achieve this.
This was apparently implemented to allow cycling between the various dash
types, but it was a bad idea bringing no benefit and causing griefs.
Useful to cache copies of objects, including shared_ptrs. No risks of dangling
pointer, and avoid naked pointers in the source.
Fix memory leak when compiling with Qt5.
As part as the backport to stable, this code has been change to work

The current version was wrong for non-English dialogs, and even for
the English one, due to the translator commands that were not removed
for calculation (as in "Formats[[output]]").
When using Qt stuff in breakAt, it may happen that the row is broken
after an hyphen (whereas the old code would only consider spaces).
The fact that we abuse the Row::right_boundary() property to detect when
a row should be flushed broke justification when a row is cut at an
hyphen.
Fix this by introducing a new Row::flushed() property and set it as needed.
(cherry picked from commit 8e7d0c2002)
The code that tries to decide whether it is worth splitting a given
text row element had a shortcoming: it did not take into account the
left margin of the new row that would be created.
The problem is that this left margin is not the same as the left
margin of the current row, because there can be for example
indentation effects.
To fix this problem, we pass the amount of available space on the
next row as a parameter of Row::shortenIfNeeded.
Note that there is no need to care about RtL row elements at this
point, since the bidi algorithm will be applied to the row
subsequently.

They are still not handled in LaTeX output, though.

Whenever an argument delimiter is used inside the argument, the argument
needs to be grouped, that is
\cites({text (text) text})
or
\cite[{text [text] text}]
This fixes the original case reported in #2751 which is independent
from the general issue that the pre- and postnote field take literal
code.
It seems that QTextLayout does not handle properly a single character
with 0 width. This breaks drawing of things like \not.
No status line needed as this amends 24648404.
When cloning InsetExternal, the tempname_ member of InsetExternalParams
has yet to be initialized. So, trying to remove it causes the warning
"QFile::remove: Empty or null file name".
