bug#5130: 23.1.50; Re: BibTeX completion via completion-in-region

["Roland Winkler" <Roland.Winkler@physik.uni-erlangen.de>]

Recently (2009-12-03) Stefan changed bibtex-complete-internal so
that now it uses completion-in-region. This results in the following
problem (as discussed already on emacs-devel):

A solution would be that BibTeX mode could set
minibuffer-message-timeout to 0 so that minibuffer-message does not
display its message. Instead bibtex-complete-string-cleanup could
display in one message the expansion of the BibTeX string and
whether this string was a "sole completion" or a "complete, but not
unique" completion.
