resolve: when resolve.mark-check=abort, downgrade to warning if pats specified

Previously, with --config resolve.mark-check=abort, running `hg resolve -m foo`
would abort and emit a message saying to use --all.  This command does not work,
though: `hg resolve -m foo --all`, and it's really weird for --all to be the
"--force" flag.

My original goal with the option was to make it so that `hg resolve -m` (no
filename arguments) was safer, which is why --all is used; in my mind, `hg
resolve -m foo` should always mark it as resolved, and `--all` is how you
specify "all the files", so that's why I chose `hg resolve -m --all` as the way
out of `hg resolve -m` aborting. This commit makes all of this work the way it
was meant to in my head :)

#require test-repo

  $ . "$TESTDIR/helpers-testrepo.sh"
  $ cd "`dirname "$TESTDIR"`"

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'
  [1]

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-module-imports.t \
  > -X tests/test-check-pyflakes.t \
  > -X tests/test-check-shbang.t
  [1]

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")'
