How to change order of completions?

[reckoner <reckoner@xxxxxxxxx>]

Hi,

I have a long list of latex files such as

   file.tex , file.dvi, file.log, file.aux

and I would like to complete on the *.tex files before any other file. 
In other words, when I do

% vi file<TAB>

I would like to have

% vi file.tex

instead of file.aux.

Any help appreciated!
