Makes sense.

The new comment given to the function in the previous step talks
in terms of the variable name and not type, so technically it is
still valid after this change without updating.

I however wonder if it makes more sense to go one step further and
rename the "const char *" variable that is a string form of a single
refspec item to something other than "refspec".  Which would
invalidate the commit you gave to the function and make it necessary
to be updated in this step.

I wonder if the early part of the series becomes easier to read if
patches 2 and 3 are swapped.  That may result in less code/comment
