match: drop unnecessary wrapping of regex in group
It seems the regexes have been wrapped in an unnamed group since
b6c42714d900 (Add locate command., 2005-07-05). In that commit, the
grouping was needed because there was a "head" ('^') added before the
group and a "tail" (os.sep) added after it. It seems the head was
moved inside the group in
1c0c413cccdd (Get add and locate to use new
repo and dirstate walk code., 2005-07-18) and the tail was moved
inside the group in
89985a1b3427 (Clean up walk and changes code to
use normalised names properly., 2005-07-31), So it seems to me that
we've carried around the unnecessary group for 13 years. This patch
removes it.
