rbenv version shows symlinks acting like aliases #637

Commits on Oct 16, 2014

  1. Have rbenv version print info about symlinks acting like aliases 

    Example:

    $ rbenv versions
      system
      1.8.7 -> 1.8.7-p375
      1.8.7-p375
      rbx -> rbx-2.2.10
      rbx-2.2.10

  2. Skip version aliases while rehashing 

    Because a version alias points to another version in rbenv, its
executables will get included in the rehash process anyway.

I hoped that this results in rehash speedup because fewer directories
get processed on a system with lots of aliases (I have 9), but the truth
is I didn't witness any speedup. It's likely that the overhead of
`rbenv-versions --skip-aliases` makes up for any performance gain that
we could have had here.
