title: GIT: is a tag unique per commit?
body: <p>If you can use a tag only once (unique by commit), what do I do with 7 commits in tag "<code>Version 7.3</code>"?<br>
  I hate that GIT doesn't make revision numbers (like SVN :)).</p>
  
  <p>I guess a subquestion would be:<br>
  What would be a best practice to 'control' version numbers (ex revisions, so I want to save <code>major.minor</code> in every commit and DEFINITELY in every branch (I make >= 1 branch per minor)).</p>
  
  <p>The first question has a factual answer (I think).<br>
  The second is more of a best practice probe.</p>
  
  <p>Much appreciated! I have learned much GIT from stackoverflow FTW!</p>
