We could also try to use the same UI as in e.g. Dired:

- in a *vc-change-log* buffer use 'm' to mark revisions;
- type 'C' to copy or 'M' to move (actually 'R' in Dired);
- select a branch name in the minibuffer with completion.

I think it makes sense to implement these commands only when they
use backend commands.  Because using diff commands is already easy
with 'C-c RET a'.  These new commands could provide an alternative way
by relying on backend commands.
