rHG3da7bf75fdb2: rust-revset: support explicit `.` revision
Summary

This is basically the same thing as not specifying a revision, except this is
done in the revset resolution function.

This allows calls like rhg cat some-file -r . to work without falling back.

Turns out there is a small problem with git subrepos, I'll fix that.

I've changed this to rev_for_node to account for D11415 getting queued since you sent this.

I pushed this series to hg-committed many hours ago. I thought that used to close the review, but it's still open here. Any idea why?

Looks like some of the infra is broken because of bad Let's Encrypt certificates, which unfortunately includes this as well as the Heptapod sync. I'll try to look into it.
