I see there is a hook already in vc: 'vc-post-command-functions'.
But it's unclear how to use it to call 'shrink-window-if-larger-than-buffer'
from the hook only on vc-log and vc-diff commands.

Maybe vc-log-internal-common and vc-diff-internal could provide new hooks,
e.g. vc-log-post-command-functions and vc-diff-post-command-functions.
