Subject: Fixed libbe.rcs.RCS.installed to handle missing backend binary.
X-Git-Tag: 1.0.0~68^2~2
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=3cc479535865e3e1948ce8812f12e1d0a34031c8;p=be.git

Fixed libbe.rcs.RCS.installed to handle missing backend binary.

This makes all the failed tests understandable, since they all crash
with strings like:
  AssertionError: Arch RCS not found
Which makes more sense than spitting out the raw CommandError.

It also means that installed_rcs() actually works now ;).
