Properly decode post-commit svn diff contents to Unicode.
Review Request #5845 — Created May 20, 2014 and submitted
SCMTool.get_changeis expected to return a Commit object with a 'diff'
parameter that is a unicode object. The SVN libraries both return diffs in
string format, which need to be decoded.
Ran unit tests.
