I was commenting on the "while (@o1)" loop that splices at 50
when the list has more than 55 items to feed update-index.  You
could accumulate output from multiple invocations of ls-files
and feed everything to a single "update-index --stdin" after the
"while (@old)" loop is done.  Batch of 50 vs a single batch may
not matter though [*1*].

But you are right; that git-ls-files can get too many arguments
unless you split like that.

A casual skimming over the rest of the code tells me that this
fixes the last instance of such a command invocation with too
many arguments.  Good catch.

Smurf, I do not have problems with Sasha's patch.  Are you OK
if I apply it?
