paths: add an argument to format the suboption display

We will use it in the next function to the delta policy display. It could also
be use to deal with the other special case in the command code, but that is
unnecessary churn for stable so that part will go on default.

#require no-windows no-rhg

XXX-RHG this test hangs if `hg` is really `rhg`. This was hidden by the use of
`alias hg=rhg` by run-tests.py. With such alias removed, this test is revealed
buggy. This need to be resolved sooner than later.

Kludge to emulate timeout(1) which is not generally available.
