Subject: Put bd into read-only mode in becommands/diff.py.
X-Git-Tag: 1.0.0~62^2~46^2~9^2~5
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=2cc6145453fd50fb034e7578362159484ab8e6e7;p=be.git

Put bd into read-only mode in becommands/diff.py.

Otherwise comment comparison reads were triggering notice of the
  None -> EMPTY
transition in comment.extra_strings, which was causing a write to
disk.  This trigger is probably occuring in Bug and BugDir too.
Perhaps I should just remove the trigger...
