Subject: Re: bug#63949: 30.0.50; `vc-print-log´ does not erase buffer when called from *vc-change-log* buffer, at least for CVS logs

Caused by commit d494833d47968fcd97ba549654a259d6fb6c2eee.

There is another subtle change to (most likely) that, which seems to 
affect all backends: When calling `vc-print-log' from 
*vc-change-buffer*, it now modifies the VC parent buffer to itself, 
which is of course incorrect.
