The variable CPACK_DEBIAN_PACKAGE_RELEASE has to be in the form
of "^[A-Za-z0-9.+~]+$". We will use the abbreviated commit revision for now.
Without this change cmake 3.10 emits error.

In some cases, it is possible that the BufferPositionMap has
dangling pointers. We thus check whether the Buffer is loaded
before accessing it.
Fixes: #10766
(cherry picked from commit 4f50cbcfe4)
The code in InsetLabel::updateReferences code changes reference insets
in potentially several buffers. When recording undo, it is important
to use the right undo stack, otherwise crashes can ensue.
Once it is done, it is neccessary to create undo groups as needed.
This is done using UndoGroupHelper. This demonstrates a shortcoming of
UndoGroupHelper: if a buffer is encountered in two seperate
occasions, two undo groups will be created for this buffer. This is
not correct.
Fixes bug #10643.

It was not a good idea to rely on QTextLine::naturalTextWidth() to
compute a string width. The correct method is horizontalAdvance().
Also round the value to the nearest pixel, since this is what
QFontMetrics::width() does.
By contrast with the code in 2.3.x/master, this code had to be adapted
for Qt < 4.7, where horizontalAdvance() is not defined and
naturalTextWidth() has to be used instead. The fix is thus only
effective starting from Qt 4.7.
Fixes bug #10700 (and maybe others).

The renaming happened in 2013. Contrary to what is stated in the
babel-vietnamese manual, option "vietnam" does not work anymore.
Also, the special care is not needed anymore, since language options
are not hardcoded anymore in babel.
Fixes: #10743
We do not want the cleanup work to be interrupted by a buffer exception.
Spotted by coverity. See bug #9979 for discussion.

This is a consequence of 060a9664, although it is not clear why. The
contextMenuEvent code of the workarea should not delegate context
menu when it cannot honor it.
Also fix a small memory leak.
Fixes bug #10616.

This fixes an error in the preview generation with polyglossia
and bidi that prevents snippet generation (and consequently also
"math as image" xhtml output).
Fixes: #10716.
In some (not yet understood) situations, the paragraph metrics cache
is empty in generateSyntheticMouseEvent(). We just avoid a crash in
this case, but there is probably an underlying problem that deserves
being fixed.
Fixes bug #10324.
(cherry picked from commit 4efb129ccb)
While 1c07c0dc was too strong and broke mathed, 4499680b is too
lenient and can accept insets (mathed/CommandInset, InsetInfo) that
have a positive nargs() but are not editable (because they encapsulate
something).
Therefore the best solution for now is to use editable() in text and
isActive() in mathed, until those two things are merged.
Part of #10667.
(cherry picked from commit 13c3c1485b)
This is a relic from IU (Inset Unification): editable() is for text
insets and isActive() for mathed. This needs to be cleaned up.
Part of bug #10667.

Without this setCurrentFont() is not correctly called on the
BufferView cursor and the cursor could appear in L-form.
Fixes bug #10686.
(cherry picked from commit 5d7dae9e38)
This issue was already addressed in the all_sel case. It only happens
at specific zoom and jusification values.
Fixes part of #8883.
(cherry picked from commit 71563835c7)
The test added at 359aef92 was incorrect. Actually, Inset::editXY
returns the inset when it is edited and also when it is not, which
can be confusing. So if we are unlucky and the slices positions in the
text area and in the inner inset match, the code below triggers and
many bad things can happen.
Also improve the documentation of Inset::editXY and TextMetrics::editXY.
Fixes#10691.

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.
(cherry picked from commit 5354c64b27)
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.
