[Tracker] Indexing LaTeX files

[rsmith whistlin com (Regis Smith)]

Tracker doesn't seem to index text files with extension *.tex.  Is there
a way to force it to do so?  Curiously, Tracker by default indexes the
RCS revision files with *.tex,v extension (undesirable, but
configurable) but not the actual *.tex file.  Apologies if I'm totally
missing something obvious.  I'm using 0.6.3.
