Summary

Fixes T8768. See PHI294. See that task for more details.

Git, Mercurial, diff, and patch have conspired to make things weird. To correctly handle files with spaces in the way everything else does and expects, we need to emit semantic trailing whitespace literals.

Test Plan
  • Created a file with spaces in it in a Mercurial repositroy, committed it, diffed it into a revision.
  • Used arc patch to apply the change to a clean copy of the repository.
  • Before patch: Mercurial incorrectly creates a file named X, not a file named X Y.txt.
  • After patch: arc patch commit is identical to genuine commit.
  • Also added test coverage. The other general behaviors here are fairly well covered already.
