branch: master
commit ca528f7c6ac9b907564298bc96663579d09f9434
Author: Arash Esbati <arash@gnu.org>
Commit: Arash Esbati <arash@gnu.org>
Suppress bogus messages in the echo area
* lisp/textmodes/reftex-dcr.el (reftex-view-crossref-when-idle):
Check if point inside a mandatory argument where the cite/ref key
usually resides. For example, with \cite[45]{emacs:30} and point
on 4, the following bogus message in the echo area is suppressed:
"cite: no such database entry: \cite[45]". (bug#38258)
Fix docstring.
