From: Pierre Habouzit Date: Tue, 14 Nov 2006 01:01:25 +0000 (+0100) Subject: begin to rework mailcap parsing a "bit". X-Git-Url: http://git.madism.org/?a=commitdiff_plain;h=49081299c673ceebc38d9a4f0985608cb3aecfce;p=apps%2Fmadmutt.git begin to rework mailcap parsing a "bit". the current way is really really really completely naïve (the mailcap parse is done many times whereas it just should be put into structs once for all !).
