@findex vc-region-history
A useful variant of examining changes is provided by the command
@kbd{vc-region-history}, which shows a @file{*VC-history*} buffer with
the history of changes to the region of the current file between point
and the mark (@pxref{Mark}). The history of changes includes the
commit log messages and also the changes themselves in the Diff
format.
Invoke this command after marking the region of the current file in
whose changes you are interested. In the @file{*VC-history*} buffer
it pops up, you can use all of the commands available in the
@file{*vc-change-log*} buffer described above, and also the commands
defined by Diff mode (@pxref{Diff Mode}).
This command is currently available only with Git.
