files: don't recurse into subrepos without a path or -S (issue5127)

The 'm.always()' check was needed for when a path to 'sub1' is given, and 'sub1'
contains a subrepo itself.  But that also caused the automatic recursion when no
path was given.  Instead, force -S when printing a subrepo if the subpath is an
exact match (which will unconditionally recurse once in the nested subrepo).

# Dummy extension that adds a delay after acquiring a lock.
#
# This extension can be used to test race conditions between lock acquisition.
