Ah, yes.  I must have bumped into this at the time, but it was so long
ago that I forgot; sorry.

At the time, I asked the Sed maintainer to fix this, so that users
could link Sed with their library's regex routines.  I think he
agreed, but since we never saw another pretest, that's a moot point
for now.

I'd suggest to name the Sed binary with NLS sed.exe, not gsed.exe.
That way, people who want the new features will be able to install the
new version on top of the old one and use it from there on without the
need to rename it.  People who do not need the new features might not
want to pay the performance price, and so will not upgrade.  We will
keep sed302[sb].zip archives on SimTel.NET at least until this issue
is resolved, so users will have the choice.
