[PATCH] i18n: factorize even more 'incompatible options' messages

[PATCH] i18n: factorize even more 'incompatible options' messages

[René Scharfe]

Continue the work of 12909b6b8a (i18n: turn "options are incompatible"
into "cannot be used together", 2022-01-05) and a699367bb8 (i18n:
factorize more 'incompatible options' messages, 2022-01-31) to use the
same parameterized error message for reporting incompatible command line
options.  This reduces the number of strings to translate and makes the
UI slightly more consistent.

Thanks for tackling this.

A couple additional instances recently slipped into `show-ref.c` which
were caught during review[1,2] but nevertheless made it to
"master"[3,4]. This patch, of course, doesn't need to address those,
but if rerolling for some other reason, perhaps they can be included,
as well(?).

[4] changes the message added by [3], so that's one instance, right?

Subject: [PATCH] show-ref: use die_for_incompatible_opt3()

Use the standard message for reporting the use of multiple mutually
exclusive options by calling die_for_incompatible_opt3() instead of
rolling our own.  This has the benefits of showing only the actually
given options, reducing the number of strings to translate and making
the UI slightly more consistent.

Adjust the test to no longer insist on a specific order of the
reported options, as this implementation detail does not affect the
usefulness of the error message.

Yes, correct. Sorry for misleadingly saying there were two new
messages; it's been a month since I looked at the patches closely, and
forgot that it was just the single message which had been modified by
the subsequent patch.

Thanks for taking care of this so quickly!

Apparently, I haven't been following along closely enough, thus wasn't
aware that we had the die_for_incompatible_opt*() family of functions.
Neat.

Ah, I wasn't aware of these new wrappers, either. The below patch looks
good to me, thanks for the fixup.
