bug#7302: vcdiff using "sccs get" rather than "get" breaks bitkeeper usage.

[Paul Bristow]

GNU Emacs 23.2.1 (x86_64-pc-linux-gnu, GTK+ Version 2.20.1) of 2010-08-15 on barber, modified by Debian

 

I previously used Emacs 21.4 and its version of the vcdiff script is compatible with bk as it just calls “get” and bitkeeper supplies a get command.  In 23.2.1 the command is “sccs get” but there is no sccs with bitkeeper.

 

Although I do not make much use of “M-x vc-diff” and could just use something different instead it does cause some problems as I have my “EDITOR” set to emacs in the environment and therefore when I fix merge conflicts in bitkeeper the file is passed to emacs.  The call to emacs always fails like so:

/usr/lib/emacs/23.2/x86_64-linux-gnu/vcdiff: 113: sccs: not found

 

I have found that reverting to the old behaviour with the patch that I have included below solves the problem.  Perhaps the change might be reverted or parameterised in future releases?

 

Regards,

  Paul Bristow.
