util: fix %-formatting on docstring by moving a closing parenthesis
We have to do the % formatting over the sysstr, since the things we're
going to splat into it are themselves sysstrs. This is probably
technically wrong-ish, since bt is probably actually a bytestr here,
but this fixes the immediate issue, which was that hg was broken on
Python 3.
