Agreed; we should be using the same coding pattern wherever we call
ftello.
I suspect that this code may be left over from coping with some ancient
non-spec-compliant version of ftello? Probably not worth digging in
the archives to find out. The Single Unix Spec v2 says that the result
is (off_t) -1 on error, and we generally assume that platforms are at
least compliant with that.
grep shows me a couple of other places where the result of ftello doesn't
seem to be getting checked for error. Odd that Coverity didn't notice
those.
