3e655e7d4c Dispatch a "diff.willBuildMessage" event from Arcanist
Summary:
Hive has custom integration which relies on prefilling a bunch of information from JIRA. This is currently broken and accomplished in a roundabout way. Instead, add an event that the integration can listen for. See next diff.

@Girish, I guess you're official Phabricator/Hive support now?

Test Plan: Ran the Hive/JIRA workflows in Git and SVN, see next diff.

of passing that argument through to a conduit call and then printing the

a31fc544c8 Fix "local commits" for Git and Mercurial to align with user expectations, and fix a parsing bug
Summary:
  - "git log" still includes "\n", so we're currently generating nonsense hashes like "\nabd9879bab86ad78ab...".
  - Correct the log range we use in Git. See comment. When users perform merges, their expectations about what the "included commits" and what the included changes are are different. Represent them with two different ranges.

There's no reason these should be exclusive: -m is used only on update for the
update message, and --verbatim doesn't affect the udpate message. It's also

my git commit message and also provide a message for the update from the

Essentially D2391, but with, uh, more comments?

  - I forgot that we already implemented shouldOverwriteWhenCommitMessageIsEdited(). This patch already behaves nearly correctly.
  - Requires changes in D2412.
  - Use `'edit' => 'edit'`, which does the same thing as `'edit' => true`, but is more correct after the "edit" / "create" split.
  - Under "--verbatim", always get the message "from the user", which means "from the working copy" because verbtatim disables the editor part.

56cdc31426 Fix some --only / --preview / SVN issues with Arcanist
Summary:
  - Historically, "--preview" was forbidden under SVN. No reason for that now.
  - The "--auto" patch moved the "--preview" / "--only" checks later than they should be.
  - Fix an issue with Conduit query construction in SVN.

Test Plan: Ran "arc diff --preview" in an SVN working copy. Ran "arc diff" in an SVN working copy.

83ad377bdb Read default relative commit from scratch file with newline
Summary:
When people create the .arc/default-relative-commit scratchfile with $EDITOR of
choice, their editor usually puts a newline at the end, which breaks arc diff.
We should trim the newline before using the contents of the scratchfile.

Test Plan:
ran arc diff in a working copy that contained a .arc/default-relative-commit
with a newline
