Either of these two, perhaps (I'd use the former if I were writing
this patch):

	add -i: show progress counter in the prompt
	add -i: add progress counter to the prompt

Give an order to the codebase to "become like so".  E.g.

	Report how many hunks have been processed and the total
	number of hunks in the current file in the prompt, and
	adjust the expected output in some tests.

	Signed-off-by: ...

Don't omit space after comma. or around the "." operators---if you
want to use "." here, that is.  I am not convinced it makes the code
better to use ".", though.

	print colored $prompt_color, "(", ($ix+1), "/$num) ",

is probably how I would write this, as I expect those writing Perl
would know that elements of a comma separated list fed to 'print'
are shown without any extra space in between.

Shouldn't this pattern be a bit tighter than "(.*)" (i.e. anything
can come between paren)?
