Backported from b8648dea16.
With this new command line switch a list of modules can be loaded
unconditionally. This seems to be needed for the literate programming formats,
and it is useful to work around bug #5702 as well.
This reverts commit 824fe17511.
Following discussion on ticket #8342, I am not sure anymore that this is safe for branch. Reverting does not hurt much since the annoying debug messages that were cured by this commit are already (better) fixed by the patch for #8342.
Implement a more simple and elegant integration of the R package knitr. Now,
lyxknitr.R does not need to move or copy files at all.
This also fixes a bug: when /tmp was on a different file system (e.g.
encrypted home), lyxknitr.R failed to move files to /tmp because it relied on
R's 'file.rename' function, which in turn relied on the rename function in
<stdio.h>, which was failing with the EXDEV errno.
Patch from Yihui Xie.
This assures that refs to existing labels are not being touched if a new label with a duplicate name is created, and the name then changed by the duplicate checker.
Branch candidate.

Those commands can also be used in text mode but tex2lyx tries to
translate their argument causing havoc. So, import the whole commands
as ERT.

The mhchem package treats the caret both as a shorthand for \uparrow or
as a superscript operator according to whether it is surrounded by
spaces or not. The \ce and \cf insets allow inserting spaces but there
is no provision for inserting a space after the caret, which is always
considered by LyX as a superscript operator. The solution here is to
insert a space after the caret if the superscript is empty or an empty
brace inset.
Mathed does not allow empty superscripts, so an empty brace has to be
inserted when working in LyX. On the other hand, when importing latex
code, an empty superscript is retained.
This has no effect whatsoever for normal latex code, as a space after
the caret is ignored. In any case, the output is only changed if an
empty brace inset is used as superscript. Specifically, the output is
changed from "^{{}}" to "^ {}".

Fix thinko in Undo::endUndoGroup.
Do not reset undo groups in Undo::clean
The underlying problem remains: the various VC functions should not
always reload the buffer or at least should use the parameter
clearUndo=false.
Filenames embraced in <...> can occur anywhere on the line and multiple times. This fixes for me the case that graphics included via ERT were not tracked. It also fixes#8336.
