Subject: Replaced direct filesystem read from bugdir.py with RCS mediated read.
X-Git-Tag: 1.0.0~118
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=d248dbca39e1e8a26a5aa9d39b28038690a406a0;p=be.git

Replaced direct filesystem read from bugdir.py with RCS mediated read.

Also replaced utility.FileString with StringIO() in cmdutil.py, which
allowed the removal of utility.FileString and utility.get_file.

The only remaining file().read() outside the RCS framework is the read
in utility.editor_string(), but should probably not go through the
RCS.
