Thanks. But that's not quite right either, since we currently allow '+' 
in version.

I revised [1] a bit to mention what I think the valid character set is, 
and disallow a hyphen in version. It might make sense to point to that 
from NAME, VERSION, RELEASE in the cygport documentation, rather than 
repeat it.

(That's assuming I've got the intersection of what's valid in cygport, 
calm and setup correct, of course)
