The strategy adopted in bc47054b had some drawbacks related to the way
instant preview snippets are generated. See the subthread starting at
http://www.mail-archive.com/lyx-devel@lists.lyx.org/msg187916.html
for details.
The strategy adopted in this commit is that of adding macro definitions
only for the macros actually used in a preview snippet, independently
of whether some macro was already used in a previous snippet. In this way
the snippets don't need to be changed according to whether they are
compiled as a whole or separately from each other. This fact was causing
the regeneration of a preview snippet whenever the cursor entered the
corresponding inset, even if the generated image would have not changed.
The problem of defining or redefining a macro is taken care by the
python scripts.
The escaping of symbols read from unicodesymbols was inconsistent, which lead
to wrong replacements (bug 9559). Now the escaping is consistent: unicode_reps
contains unescaped LaTeX commands, the needed escaping for LyX files is
applied in put_cmd_in_ert() and lyx2latex().
This is bug #9612. The patch is from Günter Milde. He wrote:
The patch uses the "long" macro names (\llless and \gggtr) to minimize
name-clash probability. (There is, e.g., a name clash of \lll with Babel's
polish.ldf (cf. bug #6197))
This is for people who cannot grasp the superior conventions of emacs ;)
A new argument "partial" has been added to word-upcase, word-lowcase
and word-capitalize that restores the old emacs-like behavior.
The (x)emacs bindings are updated to use the "partial" argument, and
also to bind correctly M-u and M-l (M-c is unfortunately not
available).
Fixes bug #2826.
* Provide for vector fonts only if needed.
* Make sure microtype doesn't throw a trantum in dvi mode.
* Use correct macro definition in preview insets.
In June the R-SS phrase system is replaced officially by the GHS H-P statement system in the EU.
So just in time here is support for this.
No new LaTeX package is required since the already supported package mhchem provides the statements.
