 While writing the version parsing for stem I noticed that the version spec
 [1] doesn't define how to compare empty tags and patch levels. For
 instance, if "1.2.3.4-myTag" is a greater or lower version than
 "1.2.3-myTag".

 My suggestion would be to add a note that an undefined patch is zero and
 undefined tag equates to the empty string. Ie...

 "1.2.3-myTag" == "1.2.3.0-myTag"
 "1.2.3.4" == "1.2.3.4-"

 Cheers! -Damian
