The difference between a and b being that a allows
package-long-description-ver-rel.tar.gz  whereas b requires
package-ver-rel.tar.gz ?
Frankly I'd prefer b (scales better), and I thought we'd made that
policy already (but http://www.cygwin.com/setup.html#naming doesn't
cover this). Interesting to note that the next section specifies that
the version _must_ start with a digit, which leads to the tetex
mis-parsing you highlit below.

AH yes - thus showcasing the point at hand:
"tetex" - "beta-20001218" - "cygver" is parsed as
"tetex-beta" - "20001218" - "cygver"!

However my point about -/_ was on readability, not just tetex!
