[Nmh-workers] Relative Message Numbers

[norm]

A while back, there was a discussion about relative message numbers. For 
example, 
http://lists.nongnu.org/archive/html/nmh-workers/2012-10/msg00048.html. But I 
don't believe there was a resolution. Was there?

If foobar is a message sequence then something like forbar+3, for the third 
message of foobar, would make my life a bit easier.

Even better, would be to allow forbar+3,4 and foobar forbar+3-5. Then, 
recursively, and perhaps a bit fancifully, since forbar+3-5 is a message 
sequence, forbar+3-5+2 would be meaningful. If foobar has had a least four 
messages it would denote the fourth messages of foobar.
