[PATCH 2/2] shallow: Remove unused code

[Ramsay Jones <ramsay@ramsay1.demon.co.uk>]

Commit 58babfff ("shallow.c: the 8 steps to select new commits for
.git/shallow", 05-12-2013) added a function to implement step 5 of
the quoted eight steps, namely 'remove_nonexistent_ours_in_pack()'.
This function implements an optional optimization step in the new
shallow commit selection algorithm. However, this function has no
callers. (The commented out call sites would need to change, in
order to provide information required by the function.)

Hi Junio,

This should, perhaps, be marked as RFC; if the patch to actually
use this function is coming soon, then this is not needed.
However, I suspect it could be slow in coming ... :-P

ATB,
Ramsay Jones
