[PATCH v2] branch: reject --show-current with -v

[PATCH v2] branch: reject --show-current with -v

[K Jayatheerth]

The --show-current option doesn't know how to handle verbose
logic. In such a case, we want the program to die when both flags
are used together.

I only changed the title of the commit message.
The previous one (i.e remove unnecessary verbose flag) sounded
like we are nuking the whole verbose flag.

The acked by tag exists here because this was supposed to be queued,
I am resending this to remind.
The originial discussion however is here:

Is there any reason why --show-current couldn't be made to work with 
--verbose instead of dying?

That's not what the Acked-by: tag means - you should remove it

It would be better to use die_for_incompatible_opt2() here so that the 
message is consistent with other commands.

This checks that the command fails but does not check _why_ in failed. 
It would be better to redirect stderr to a file and use test_grep to 
check the error message matches what we expect as well checking that the 
command fails.

I was about to write "Yes, I do not even recall seeing this patch",
noticed the "v2" label, but couldn't find corresponding v1.  If the
message had "In-reply-to: <xmqqldiplvyd.fsf@gitster.g>", that would
not have happened.  FWIW, Sergey, who gave the "why" to start the
thread, deserves much more credit than I would, I would have to say.

I did say "This is certainly an improvement over status quo.", and
"is good enough for now", so it is not completely unwarranted to
have my Ack there.  Without any context it is hard to see, though.

I _think_ what happened was later, after that "Ack" was given,
Sergey brought up a good point, "why not consider what should -v
mean in the context of --show-current before proceeding", which is
more or less the same as your point above, so either I did not pick
up the patch right there (expecting some form of response), or
picked it up but discarded (after seeing no response came), or
something like that.

Since there are two people who independently questioned the wisdom
of erroring out on "-v" before thinking things through to see if we
can come up with a good behaviour for "--show-current -v", perhaps
we should do so before proceeding.

So, I am not picking this iteration up, at least not yet.

Yes.  That would be much better.

Good suggestion.
