-R is needed on almost all other commands so this makes things consistent. Patch by Lorenz (xha)

We can keep accepting git+ssh for backwards compatibility with existing configs.

`.Op Fl Eq' gets rendered as [-] with groff because Eq it's a macro. Escape it to get it rendered correctly. Discussed with bentley. Reported by casaca on the IRC channel, thanks!

When an operation is interrupted add a trailing message to status output which displays the operation and branches involved. This information will be useful when diagnosing problem reports and it helps new users with contextualizing multi-operation work tree state. ok op@

Because the current implementation of toposort is expensive, add a flag which enables it. I would rather not have this option and just use toposort by default, however more work is required to achieve acceptable performance. ok op@

Otherwise copy/pasting from the man page to got.conf produces syntax errors. Noticed by mlarkin@

The 'mesg' script command now requires a commit ID as its argument, rather than being tied to a preceding 'pick' or 'edit' command. The old model was too confusing for new users, in particular for people used to Git's rebase -i squash semantics. The 'mesg' command is now semantically equivalent to the 'pick' command and additionally opens the log message in an editor. The new syntax is simpler to use but also requires that we drop support for one-line log messages inside the histedit script, with a commit ID taking its place in the argument space. We don't believe this feature was used much, and that a simplified usage model is more beneficial overall. Patch by Lorenz (xha) ok jamsek

We did consider making -d and -P options conflict but doing so would not be very helpful. Instead, document -d as a superset of -P. ok op, jamsek

Suggested by Lucas on IRC. ok stsp@ and op@

As suggested by stsp, show the out-of-date symbol for the work tree branch if it is not only out of date in relation to the branch tip but also if it contains mixed commits. Update regress and add new test to check for this case. Also, explain the mixed commit condition of * and ~ markers denoting work tree state in got(1) branch -l docs. ok stsp@

More work adding commit keyword support to the blame, cat, ref, tag, and tree commands. With this, all Got commands that take a <commit> option argument or operand now support keywords. Regress flub saved by op! fixes + ok op@

Add the ability to use keywords in the backout, branch, checkout, cherrypick, and patch commands. Includes some basic regress tests for the new commands, and also some more contrived test cases for 'got log -c[:]keyword[:(+|-)[N]]'. ok stsp
