I don't want to encourage everyone to use a buggy version, both
of 1.875 and 2.0 would be good enough.  The problem we have now
is that distributed tarball has a wrong file, caused by the
environment where it was made.  At all events, we need a new
tarball, out of doubt.

It works with some sed, but all sed doesn't work with \+ presumably.
You may need to write it as /^ *;$/d for older ones.
