[Vim-latex-cvs] vimfiles/ftplugin/latex-suite folding.vim,1.22,1.23

[<sri...@us...>]

Update of /cvsroot/vim-latex/vimfiles/ftplugin/latex-suite
In directory sc8-pr-cvs1:/tmp/cvs-serv23729

Modified Files:
	folding.vim 
Log Message:
Change: By default do not fold any commands at all. This is because the
        start pattern for a command requires a regexp which will match
        unbalanced parentheses of arbitrary depth. Apparently it can be
        proved that this cannot be done with regexps.

        Just to be on the safe side, change the start pattern for a command
        to '^\s*\\'.name.'{[^{}]*$'. This will at least ensure that no
        illegal folds are created. The limitation is that some legal folds
        might also not be created.
