rhg: Make `files` work on repo-relative paths when possible

When the current directory is outside of the repository we need to turn
everything into absolute filesystem paths in order to compute correct
relative paths.

This was previously done unconditionally, but is not necessary when
the current directory is inside the repository.

With this change `rhg files > /dev/null` at the root of a mozilla-central
snapshot goes from ~150 ms to ~70 ms. My repository is located at a
somewhat long path though (93 bytes). The effect may not be as pronounced
at a shorter path.

Mercurial
=========

Mercurial is a fast, easy to use, distributed revision control tool
for software developers.

Basic install::

 $ make            # see install targets
 $ make install    # do a system-wide install
 $ hg debuginstall # sanity-check setup
 $ hg              # see help

Running without installing::

 $ make local      # build for inplace usage
 $ ./hg --version  # should show the latest version

See https://mercurial-scm.org/ for detailed installation
instructions, platform-specific notes, and Mercurial user information.

Notes for packagers
===================

Mercurial ships a copy of the python-zstandard sources. This is used to
provide support for zstd compression and decompression functionality. The
module is not intended to be replaced by the plain python-zstandard nor
is it intended to use a system zstd library. Patches can result in hard
to diagnose errors and are explicitly discouraged as unsupported
configuration.
