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.

We already attempt to detect and prevent this condition, we just don't do a very good job of it. Fix the check so that we avoid generating overlapping hunks.
Test Plan:

- Used "arc export --git" to verify patches generate without overlapping sections.

Summary:
Adds a secret, undoucmented "encoding" key to ".arcconfig" which makes a very
half-hearted effort to convert encodings. This is probably good enough that
Differential can be used for code review, but there will be issues with 'arc
patch', 'arc export', paste, maybe conduit stuff, Diffusion, and whatever else I
haven't thought of.
This also doesn't store the original encoding so anything converted like this
won't reasonably be able to be made to work with all that stuff in the future.
See T452 for a broader discussion of the issues involved.
Test Plan:
Short circuited the UTF-8 detection to always fail, had my files "converted"
from ISO-8859-1 to UTF-8.

the 'unix:filemode' property change that will accompany the changeset. We could

good enough as-is.

In Git, Mercurial and SVN working copies ran like a million
amend/merge/commit/mark-committed commands with and without --finalize in

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.
