Subject: Reduce line buffer size in mx_get_magic().
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=9506db1e4a01fadf503b63381ab2b60dee32b836;p=mutt

Reduce line buffer size in mx_get_magic().

tmp is only used for mbox and mmdf iniital line examination.  That
only needs to look at 6 characters from the first line.
