Revision 4525e8e41a8c0c4246a95097744604ea72198dad authored by Junio C Hamano on 15 July 2009, 22:10:06 UTC, committed by Junio C Hamano on 15 July 2009, 22:10:06 UTC 
Revert "mailinfo: Remove only one set of square brackets"
 
This reverts commit 650d30d8a120c8982309ccb9ef40432b4ea2eb74.

Some mailing lists are configured add prefix "[listname] " to all their
messages, and also people hand-edit subject lines, be it an output from
format-patch or a patch generated by some other means.

We cannot stop people from mucking with the subject line, and with the
change, there always will be need for hand editing the subject when that
happens.  People have depended on the leading [bracketed string] removal.
