Cleanups, part of work on issue #414:

* reps-strings.c (rep_read_range): Removed unused var `base_rep'.
Remove obsolete comment.
(svn_fs__rep_deltify): Print numbers with "%u", not "%ul", which
should be "%lu" in any case.  The "%ul" meant we were printing the
number followed by a lower-case `l'!  The only reason this was not a
problem is that atoi() knows how to handle a trailing `l'.  We got
lucky.  But note that our repository now has a bunch of reps with l's
at the end of their size fields.  They're not doing any harm there,
except to remind me daily of my folly.
