As a general remark, it is a very good idea to keep large style(9)
sweeps separate from actual code changes even if they are tiny.
Changing style(9) shouldn't alter the binary code produced, and
this can be 100% verified using cmp(1), diff(1), cksum(1), or md5(1).
Of course, changing line numbers will affect debug info, but the
latter can be strip(1)'ed. In the case under discussion, I'd compare
if_em.o with its former version to make sure no code changed.
