If I understand, this presumes that initially latex is the default
TeX-engine, but it adds the xelatex engine to the available commands
if the expression is matched. This expression is way beyond my ken.
Would it be possible instead to put a comment line just before the
preamble of a document that contains either the word "latex" or
"xelatex" (assuming those words do not appear elsewhere in the
document) and base the forward search on it? Also, for my purposes it
would probably be more convenient to make xelatex the default
TeX-engine and if the word "latex" is found it would instead be used
as the TeX-engine. I assume this would also avoid having to enlarge
the TeX-command-list because I suppose latex would already be in it.
