why not simply use "-" and "+" where "-" is before zero-length string
and "+" is after any other string... and then sort the rest
alphabetically? f.e.

  1.0-a1-dev456
< 1.0-a1
< 1.0-a1+dev456
< 1.0-dev456
< 1.0-rc1-dev456
< 1.0-rc1
< 1.0-rc1+post123
< 1.0
< 1.0+post123

don't worry about Debian, we'll simply replace "-" with "~" (we use "~"
and "+" right now[0]). I'm not sure about rpm, but I bet it has
something similar and it will be much easier for us to simply handle two
characters instead of recognizing that dev1 < a1 < b1 < c1 == rc1 ...
