vim-patch:92f4e91: runtime(vim): Update base-syntax, allow whitespace before :substitute pattern (#29210)

Browse Source 
Allow whitespace between the :substitute command and its pattern
argument.  Although unusual, it is supported and there are examples in
the wild.

Match Vi compatible :substitute commands like :s\/{string}/.  See :help
E1270.

fixes: vim/vim#14920
closes: vim/vim#14923

By default, g:vimsyn_folding is unset. Concatenate the indicated characters
to support folding of multiple syntax constructs; i.e.
g:vimsyn_folding = "fh" will enable folding of both functions and heredocs.
*g:vimsyn_noerror*
Not all error highlighting that syntax/vim.vim does may be correct; Vim script
is a difficult language to highlight correctly. A way to suppress error
