[RFC/PATCH] sequencer: do not translate reflog messages

[Michael J Gruber <git@grubix.eu>]

Traditionally, reflog messages were never translated, in particular not
on storage.

Due to the switch of more parts of git to the sequencer, old changes in
the sequencer code may lead to recent changes in git's behaviour. E.g.:
c28cbc5ea6 ("sequencer: mark action_name() for translation", 2016-10-21)
marked several uses of `action_name()` for translation. Recently, this
lead to a partially translated reflog:

`rebase: fast-forward` is translated (e.g. in de to `Rebase: Vorspulen`)
whereas other reflog entries such as `rebase (pick):` remain
untranslated as they should be.

Change the relevant line in the sequencer so that this reflog entry
remains untranslated, as well.

The patch also changes `action_name()` not to translate the names. This
makes no difference for `rebase: fast-forward` (I don't quite grok why
so far) but in any case, the callers mark the result of `action_name()`
(or do not mark it) so that the result itself should not be translated.
The full test suite passes either way.

RFC for my lack of full grasp of the relevant code paths.
