Subject: infinite loop in git-send-email with alias files
Message-ID: <8bd0f97a0907161810w22726ffdye5c8d64719b77b53@mail.gmail.com>

i was setting up an aliasesfile for git-send-email, but in doing so, i
inadvertently made a typo creating an infinite loop.  i didnt notice
right away, but i did notice when `git-send-email` hung using 100% of
a cpu.

simple way to reproduce:
$ $ git config sendemail.aliasesfile
.git/mail
$ git config sendemail.aliasfiletype
mutt
$ cat .git/mail
alias a b
alias b a
$ git send-email HEAD^ --to a
<hit enter a few times and watch it hang>

noticed with 1.6.3.3, but seems to be in 1.6.4-rc1 too
