Summary:
Git works completely differently for commits zero and one than for 2..N so add
more special casing to handle them. See:
- {T206}
- {T596}
The getCommitRange() block is also fatal land, although I wasn't able to reach
it. I'll follow up with @s on T596.
Test Plan:
- Created a new, empty repository ("mkdir x; cd x; git init").
- Ran "arc lint", "arc unit", "arc diff" against it with no commits (the first
two work, the third fails helpfully).
- Made an initial commit.
- Ran "arc lint", "arc unit", "arc diff" against it (all work correctly).

Summary:
In D1079, I added "--color never", but this flag is provided by the "color"
extension, which is why I missed it originally, because it doesn't show up until
you enable that extension. Providing it causes installs which don't have it
enabled (disabled is the default) to fail.
Use "--config" to disable color instead. This sets a configuration setting and
works regardless of whether the color extension is present.
Test Plan: Ran "arc diff" in a mercurial working copy with the color extension
enabled and disabled.

- Revert D1061 (This reverts commit b2cd18252701be2093b52652fb3d1d94c5df571e.)
- Make getChangedLines() return null to indicate that the operation doesn't

- Fix a bug where running "arc lint" on a change in an SVN working copy from a

- Fix a bug where warnings with no line information were incorrectly
discarded.
Test Plan:
- Ran "arc lint" in an SVN working copy with a new directory (no failure).
- Forced FilenameLinter to always raise a warning. Added a binary file and ran
"arc lint". The warning was reported for the new binary file, a new text file,

Summary:
In D962, I switched us from using "hg summary" to "hg id" to find the working

working copy is dirty, so we fail before hitting the explicit check for this
later.
Trim off the trailing '+' if it is present.

See D945. We have this kludgy "remote_hooks_installed" mess right now, but we
have enough information on the server nowadays to figure this out without it.
Also reduce code duplication by sharing the "mark-committed" workflow.
This causes "arc merge" to effect commit marks.
Test Plan:
In Git, Mercurial and SVN working copies ran like a million
amend/merge/commit/mark-committed commands with and without --finalize in
various states of revision completion.
This change is really hard to exhaustively test because of the number of
combinations of VCS, revision state, command, command flags, repository state
and tracking state. All the reasonable tests I could come up with worked
correctly, though.

Summary:
This should support conservative rewrite policies in git fairly well, under an
assumed workflow of:
- Develop in local branches, never rewrite history.
- Commit with "-m" or by typing a brief, non-template commit message
describing the checkpoint.
- Provide rich information in the web console (reviewers, etc.)
- Finalize with "git checkout master && arc merge branch && git push" or some
flavor thereof.
This supports Mercurial somewhat. The major problem is that "hg merge" fails if
the local is a fastforward of the remote, at which point there's nowhere we can
throw the commit message. Oh well. Just push it and we'll do our best to link
them up based on local commit info.
I am increasingly forming an opinion that Mercurial is "saftey-scissors git".
But also maybe I have no clue what I'm doing. I just don't understand why anyone
would think it's a good idea to have a trunk consisting of ~50% known-broken
revisions, random checkpoint parts, whitespace changes, typo fixes, etc. If you
use git with branching you can avoid this by making a trunk out of merges or
with rebase/amend, but there seems to be no way to have "one commit = one idea"
in any real sense in Mercurial.
Test Plan: Execute "arc merge" in git and mercurial.
