Enrico Forestieri 72a488d7e6 Fix output of en- and em-dashes with TeX fonts
This commit fixes the regression introduced in 2.2 about the
output of en- and em-dashes. In 2.2 en- and em-dashes are output as
the \textendash and \textemdash macros when using TeX fonts, causing
changed output in old documents and also bugs (for example, #10490).

Now documents produced with older versions work again as intended,
while documents produced with 2.2 can be made to produce the exact
same output by simply checking "Don't use ligatures for en-and
em-dashes" in Document->Settings->Fonts.

When exporting documents using TeX fonts to earlier versions, in order
to avoid changed output, a zero-width space character is inserted after
each en/em-dash if dash ligatures are allowed. These characters are
removed when reloading  documents with 2.3, so that they don't accumulate.

!Important Changes in LyX 2.3.0
!!Interface changes
* LyX now has "inverted" branch insets, which output their contents just in
case a given branch is not "activated". This makes inclusion of alternate
material in different versions easier.
* When inserting a command or symbol in mathed, it is now automatically
wrapped in a real inset (either \text or \ensuremath) assuring the correct
mode, instead of being wrapped only in the output. The wrapping inset can
be safely dissolved, as it will be automatically inserted at export time
if needed, as usual.
* LyX now outputs en- and em-dashes as -- and --- ligatures when exporting to
latex using TeX fonts, as done in version 2.1 and earlier. In version 2.2
they were instead output as the macros \textendash and \textemdash, causing
changed output with old documents and bugs. The 2.2 behavior can be restored
by don't allowing using dash ligatures in Document→Settings→Fonts.
!!!The following pref variables were added in 2.3:
!!!The following pref variables were changed in 2.3:
* \document_path
Default is changed to ".". The best guess for where the user wants to save
or find files is the directory the user started LyX from. Before, the
default was always the home directory. If desired, the old behavior can be
restored by changing the default path in Preferences > "Working directory".
!!!The following pref variables are obsoleted in 2.3:
!!!The following new LyX functions have been introduced in 2.3:
* branch-invert
Toggles inversion status of branch inset.
* lyx-activate
Activates the LyX window. Useful in combination with reverse search.
!!!The following LyX functions have been changed in 2.3:
* quote-insert
The function now has a second and third optional argument to specify
the side (left, right, auto) and quotation mark style (english, swedish,
german, polish, french, danish).
* inset-modify
This function now also applies to quote insets. It takes a three-character
string as an argument, refering (1.) to the style (e = ``english'',
s = ''swedish'', g = ,,german``, p = ,,polish'', f = <<french>>, a = >>danish<<),
(2.) to the side (l = left, r = right) and (3.) to the quotation level
(s = single, d = double). So "eld" means "English left double quotation mark".
A dot in the string means: take the current value. So "inset-modify changetype e.."
will only change the style to English, while letting side and level as is,
"inset-modify changetype f.s" will change the style to French and the level to
single, leaving the side value.
This function is most useful when combined with inset-forall. E.g.,
"inset-forall Quotes inset-modify changetype f.."
=> change all quote insets to French style, maintaining current side and level
"inset-forall Quotes inset-modify changetype ..s"
=> change all quote insets to single quotes, keeping style and level
"inset-forall Quotes inset-modify changetype g.s"
=> change all quote insets to German single quotes, keeping left/right setting
!!!The following LyX documents have been moved in 2.3:
!!!The following metadata files have been added to the tarball in 2.3:
!!Changes with respect to external programs and libraries in 2.3:
* Inkscape SVG with separate LaTeX + PDF output is experimentally supported.
* Add some editor/viewer applications to (re)configure checks.
!!Known issues in version 2.3.0
!!Caveats when upgrading from earlier versions to 2.3.x
* When loading documents created with LyX 2.2, you might need to check
"Don't use ligatures for en- and em-dashes" in Document→Settings→Fonts
to avoid changed output if they contain en- or em-dashes and use TeX fonts.
You don't need to do this for documents created with earlier versions.
* If the "Use non-TeX fonts" and "Don't use ligatures for en- and em-dashes"
document preferences are not checked, when exporting documents containing
en- and em-dashes to the format of LyX 2.0 or earlier, the following line
has to be manually added to the unicodesymbols file of that LyX version:<br>
0x200b "\\hspace{0pt}" "" "" "" "" # ZERO WIDTH SPACE<br>
This avoids "uncodable character" issues if the document is actually
loaded by that LyX version. LyX 2.1 and later versions already have the
necessary definition in their unicodesymbols file.
