The patch doesn't look dangerous to me, so you can go ahead and install, 
thank you.

There is, however, a possible inconsistency: it touches 
xref--collect-matches-1, which is used both in xref-collect-matches and 
xref-collect-references. And you only changed the former function.

Could you check that M-x xref-find-references didn't work on remote 
directories before your patch anyway? If it did, though, please make 
sure that it continues to do so.

Bonus points for fixing it, at least when Grep is used (the relevant 
file is lisp/cedet/semantic/symref/grep.el).
