This patch adds a remote.<foo>.mirror configuration option that,
when set, automatically puts git-push in --mirror mode for that
remote.
Furthermore, the option is set automatically by `git remote
add --mirror'.
The code in remote.c to parse remote.<foo>skipdefaultupdate
had a subtle problem: a comment in the code indicated that
special care was needed for boolean options, but this care was
not used in parsing the option. Since I was touching related
code, I did this fix too.
