[PATCH 4/4 v2] sequencer: spell out command names and do not translate them

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

When we talk about sequencer action names as such we do translate the
action name. In all cases, we talk about the like-named git command
name, though, which is not translated.

In order to make the correspondence clearer, reword those error messages
to use the (untranslated) git command name, and adjust the po README to
match the code base.

I guess there are two extreme views regarding these cases (in terms of
how much to translate) and a few in between. v2 here implements the
one of these. As a result, we don't need to N_()-mark the action names
any more unless I'm overlooking something. I'm holding this back until
the consensus is clear.

Overall, we are not consistent with the prefixes in our error messages
(command or not) nor the capitalisation. One could say that at the point
of an error/die worse has gone wrong than the wording, of course ;)
