Summary:
XHPAST encounters a parse-depth problem on some files because PHP
5.2 has an un-overridable parse depth limit for JSON. The text of this error
says it is a "warning" but we currently raise an error. Make it a warning
instead.
The JSON depth is 20 until PHP 5.2.3, where it becomes 128. After PHP 5.3
it defaults to 512 and is user-configurable, which will allow us to resolve
this issue in nearly all cases.
Since I made if/else express as a list in the AST, this only actually arises
in long binary chains, most commonly string concatenation, like:
$out = 'a'.'a'.'a'.'a'...
...where each string is a variable or HTML tag and the program is constructing
a complicated document.
At some point I'll add some PHP 5.3 massaging to the XHPAST decoder itself to
raise this limit to something more huge.
Test Plan:
Ran "arc lint --lintall" on a file with a very deep binary
expression tree ("1 + 1 + 1 ...") and received a warning instead of an error.

Summary:
If you had changes to a directory covered by a .arcconfig residing
inside another directory also covered by an .arcconfig, the hook would
incorrectly attribute the first file it attempted to resolve to the topmost
.arcconfig because it failed to break out of the loop after resolving it.
All other files would be correctly attributed, because they'd hit the cache.
Test Plan:
Created an svn repository and checked it out locally. Created a
structure like this:
.arcconfig
shallow
a/
b/
c/
.arcconfig
d/
deep
deep2
deep3
Made modifications to "deep", "deep2", and "deep3". Received an error message
about multiple .arcconfig changes, attributing one file to the topmost
arcconfig and the other two to the deeper one.
Applied patch.
Commit now goes through. Made a commit affecting 'shallow' and 'deep' and
'deep2', commit was correctly blocked and files were attributed to the
corresponding .arcconfigs.

Some PHP installs don't have this by default. Do a conditional check
since this functionality is noncritical.

Summary: Haiping is getting a pretty confusing error message when trying to
commit.
Test Plan: Created a mock repository, installed the hook, made commits against
directories with bad .arcconfigs.

Summary: When running "arc diff" in a mixed-base-revision working copy, we
prevent the operation. Relax this restriction so that having a different root
revision is okay, so long as all affected files share the same revision. This
facilitates multiple similar edits without updates.
Test Plan: Reverted a file to an older revision in an SVN working copy, ran
"arc diff", was rejected. Applied patch, ran "arc diff", diff went through and
was recorded with the right SVN base revision in the database.

Summary: We sync from local right now, which is fairly terrible. But
fixing this correctly is also not trivial and I don't have the right
primitives yet.

Summary: The biggest blocker on getting rid of arc in trunk is that the lint
rules in the commit hooks are still running the old version. Push arc
commit hook support toward some reasonable state of approximately working.

Summary: The multi-line comment regexp was potentially too greedy. See
"greedy.lint-test".
- Made it less greedy.
- Added test coverage.
- Fixed an issue with the Apache license getting applied with too much
whitespace against C files.
Test Plan: Ran unit tests.
