This is a real problem.  Diff mode requires typing a long sequence of
'C-c C-a C-c C-a C-c C-a C-c C-a ...' to apply the whole diff.

A possible solution would be to support a region by 'C-c C-a'.
Then it will be possible to activate the region on the whole buffer
or on a few hunks, and type a single 'C-c C-a'.

Another problem that the changes are not saved automatically
on multiple files.  This limitation forces to use tricks like
'M-| git apply RET' after selecting the whole diff buffer with 'C-x h'
or a region of the diff buffer.  A "poor man's auto-save".
