All the contributors (me, Timo and Philip) have done the paperwork, and I'd like for vc-got to be included in ELPA.

I don't know why I bothered with `got tree' to get the object id and stuff. `got cat' accepts filenames and does the trick. While there, also drop vc-got--tree-parse and vc-got--tree as they're now unused.

Diff from Philip Kaludercic (philipk [AT] posteo net) with minor tweaks by me, thanks a lot!

initialize the log-edit buffer with `Summary: tag <version>'

`got send' uses \r to "update" the outputted text; it's nice and why don't support it? Without this, Emacs wait for a \n and output a long line with various ^M inside; it's ugly. While there, there's no need to call (vc-compilation-mode 'git), so replace it with 'got.

* add the needed requires, now it byte-compiles fine with emacs-27.2 (emacs-28 was always fine) * setq-local didn't support multiple values until not so logn ago IIRC

log-outgoing used to include also the latest commit in REMOTE-LOCATION, and it's misleading (i.e. vc-log-outgoing on a sync'd repository would still list a commit). This fixes it by calling next-revision on the remote-location, which is nil when we're in sync with upstream.
