Re: [PATCH 2/2] builtin/symbolic-ref.c: add option to output shortened ref

Jan Krüger [off-list ref] writes:

In scripts meant to generate user-consumable output, it can be helpful
to resolve a symbolic ref and output the result in a shortened form,
such as for use in shell prompts. Add a new -s option to allow this.

I think this one (unlike 1/2) makes sense, but a single letter -s feels a
bit too vague.  Always spelling in long option "--short" so that it
matches "%(refname:short)" in for-each-ref might be better, I would think.

Especially given that the expected use case is primarily in scripts not
from the command line, being more explicit and easier to read has value
over being short and easier to (mis)type.
