[mew-int 00404] Simple improvement for body greps

[David A. Panariti]

Hi,

Setting mew-prog-grep-opts to '("-l" "-e") can help speed things up,
especially for large message bodies that may be very large mime
files.  The -l says just print the file name and exit after the *first*
match.  Since we don't need the match text and don't need additional
match info, using it can only help.  Of course, most of the time the
difference will be insignifican, but we still might as well save the
cycles. 

Summary:

(setq mew-prog-grep-opts '("-l" "-e"))

Thanks to the mew developers for such a good system.

regards,
