I'm not sure if we are interested in this kind of linters ("Don't use slow function if there is a fast alternative").
I didn't find a case where `strpos() === 0` could be useful except [[ http://www.php.net/manual/en/mbstring.overload.php | mbstring.func_overload ]] craziness.

extraData provides more scope for extensions to piggy-back
more data on the test results and have that pulled up to the UI.
We're using keys like "facebook:complexity" to store additional
data as part of the test results.
Test Plan:
Nothing in the codebase touches extraData at the moment, so
you'll just have to have faith/prove by inspection.

We shove alias parameters onto the front of the arg list so if you make an alias like "qdiff" = "diff x y z" and then run "qdiff a b c", we end up with "diff x y z a b c". However, currently we reverse alias parameters, so you actually get "diff z y x a b c".
This is a problem for `arc alias bdiff -- diff --background 1`, which evaluates to `arc diff 1 --background` and fails.

Summary:
I usually write commit messages 1-2 minutes.
`arc lint` in our repository usually runs for around 30 seconds, `arc unit` another minute or two.
Even Phabricator unit tests sometimes runs long (because `CREATE DATABASE` and `DROP DATABASE` is slow in our setup for some reason).
Waiting for the results is boring and unnecessary.
This diff presents two different concepts how to run them on background:
# Lint is run with `--output json`, results are parsed and presented back to user. It isn't perfect - there's no context in printed lint errors which is a serious problem.
# Unit tests are run normally and the results are written to a scratch file. It also isn't perfect - colors are lost during the process.
I'll probably choose one approach and use it on both places. Let me know your thoughts about them.
This can be further improved to resolve the futures also after inputting the update message but it can be done in a separate diff.
Test Plan:
- Remove lint engine.
- Remove unit engine.
- Make lint errors.
- Make unit errors.

Currently, when the user types `arc set-config x false`, we set it as the string "false", which is usually not desirable. We have some steps toward typed config already, but expand on what we have and move as much stuff as possible into it, including all the config settings that aren't currently documented (there are still some lint-specific and project-specific settings not present here, but this is most of it).
Also make the `phutil_libraries` key a legacy name for `load`, and `immutable_history` a legacy name for `history.immutable`. Generally the goal here is to make config simpler and bring it more in-line with Git/Mercurial, which use dotted hierarchies.
I'll add some documentation here but I think most of the changes should be fairly straightforward.
Test Plan:
- `arc set-config history.immutable on` (And similar -- sets to boolean true.)
- `arc set-config history.immutable off` (And similar -- sets to boolean false.)
- `arc set-config history.immutable derp` (And similar -- raises exception.)

Summary:
- In "arc which", we recommend "--rev x --rev ." to show changes. This is not accurate if there are uncommitted changes in the working copy. Just "--rev x" shows the correct changes (implicitly, the other end of the range is the working copy state).
- When you diff only working copy changes, we currently incorrectly identify all your open revisions as belonging to the working copy. Instead, correctly identify none of them as belonging to the working copy (in theory, we could go farther than this and do path-based identification like SVN, but with --amend in hg 2.2+ this workflow should be going away in the long run).
- If you have uncommitted working copy changes, never try to amend.
