copies: avoid materializing a full directory map during copy tracing
Materializing a full copy of every directory in a treemanifest repo can be quite
expensive, even with a narrow matcher. For flat manifest repos, this should be
equivalent - it will still materialize (and cache) a dict of all of the dirs
inside of the manifest object, we just don't get a copy of it.
In a repo I have here, this brings the time for a simple rebase from 11.197s to
4.609s.

look for python scripts that do not use /usr/bin/env
$ testrepohg files 'set:grep(r"^#!.*?python") and not grep(r"^#!/usr/bi{1}n/env python") - **/*.t'

In tests, enforce $PYTHON and *not* /usr/bin/env python or similar:
$ testrepohg files 'set:grep(r"#!.*?python") and **/*.t' \
> -X tests/test-check-execute.t \
> -X tests/test-check-format.t \
> -X tests/test-check-module-imports.t \
> -X tests/test-check-pyflakes.t \
> -X tests/test-check-shbang.t

The above exclusions are because they're looking for files that
contain Python but don't end in .py - please avoid adding more.
look for shell scripts that do not use /bin/sh
$ testrepohg files 'set:grep(r"^#!.*/bi{1}n/sh") and not grep(r"^#!/bi{1}n/sh")'
