Please clarify "unwanted" in the proposed commit log message.
It looks to me that the assignment very much deliberate. We know
refnames and 40-hex object names do not contain SP, and the hook is
fed (quoting from Documentation/githooks.txt) like this:
Information about what is to be pushed is provided on the hook's standard
input with lines of the form:
<local ref> SP <local sha1> SP <remote ref> SP <remote sha1> LF
so setting IFS to SP alone smells as an attempt to ensure that the
"read" in each loop iteration would split at SP and nothing else;
Aaron Schrab CC'ed who did the original in 87c86dd1 (Add sample
pre-push hook script, 2013-01-13).
Also you would notice by reading "git shortlog" of our history that
s/Remove/remove/ on the subject line would avoid this entry stand out
among others unnecessarily, but that is minor.
