check-commit: remove confusion between summary line and other headers The pull url header can easily grow over 80 chars. The check-commit script was confusing this with a too long summary line. We update the regular expression to not match other header.

shelve: execute checkunfinished inside wlock scope Before this patch, "hg shelve" of shelve extension executes 'cmdutil.checkunfinished()' before acquisition of wlock.

This also fixes issue4957, because now 'cmdutil.checkunfinished()' isn't invoked at "hg shelve" with options below: --cleanup --delete --list --patch --stat
