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 :)
