This fixes three issues I ran into when running tests against the legacy ClearCase
implementation. Specifically:

  • When running on Python 3, there were some unicode-vs-bytes bugs in the diff parsing.
  • If the diff had incorrectly formatted filenames (which didn't include the vobtag),
    the diff parsing stage could infinite loop. I've added a fallback to ensure we don't
    loop more than a limited number of times.
  • The path normalization for display was calling realpath on a relative path, which
    (on Linux) would end up adding the CWD to the path. I've changed it so we first turn it
    into an absolute path relative to the repo root, run realpath, and then make it
    relative again.

Posted some changes using a dynamic view as the backend. Saw that I could post changes
without any errors, and that paths for files were displayed correctly.

Let's encode this once outside of the loop.
