Yes, indeed, there was an old sort syntax, where they supported it in a for=
m "+POS1 -POS2". It is a non-POSIX obsolete syntax, so we did not implement=
it in the new BSD sort. I can add it, if necessary.
Regards,
Oleg

As it turns out, this *is* something that Gnu sort supports, although
the documentation claims that the syntax is obsolete -- and doesn't
document it very well.

It wouldn't be bad if BSD sort supported it, but it should definitely be
fixed in the ports Makefile. I have submitted the fix in a PR:
http://www.freebsd.org/cgi/query-pr.cgi?pr=3D166188
Personally, I'd don't see any reason for bsdsort to include this
functionality...
