The code assumes that at this point $curr_branch has the result of
git symbolic-ref -q HEAD it did at the beginning, before it entered
in the command line parsing loop.  But immediately after it, the
code sets up $curr_branch_short for the value this code computes.

So it appears to me that the above two lines that are not updated
would introduce a regression.  Am I missing something trivial?

Puzzled.

If $curr_branch in the original code was (wasn't) an empty string,
then with the updated code that does not strip refs/heads/ from the
beginning of it after applying the first hunk of this patch, the
variable is (isn't) an empty string, respectively. So there is no
need for this hunk, I think.
