bug#53749: 29.0.50; [PATCH] Xref backend for TeX buffers

[David Fussner via "Bug reports for GNU Emacs, the Swiss army knife of text editors" <bug-gnu-emacs@gnu.org>]

Thank you, Stefan -- I didn't know about
major-mode-remap-alist/defaults. Do you think TeX and friends are
handled by emacs distinctively enough to warrant keeping some
specialist extension-handling code in tex-mode.el, or do you think
some changes should be more generally available, in grep.el, say? (I'm
wondering whether it might be useful, for example, for
semantic-symref-derive-find-filepatterns to add extensions from
auto-mode-alist even when some extensions are found in
semantic-symref-filepattern-alist.)

David.
