   8  * A struct refspec_item holds the parsed interpretation of a refspec.  If it
   9  * will force updates (starts with a '+'), force is true.  If it is a pattern
  10  * (sides end with '*') pattern is true.  If it is a negative refspec, (starts
  11  * with '^'), negative is true.  src and dest are the two sides (including '*'
  12  * characters if present); if there is only one side, it is src, and dst is
  13  * NULL; if sides exist but are empty (i.e., the refspec either starts or ends
  14  * with ':'), the corresponding side is "".
  15  *
  16  * remote_find_tracking(), given a remote and a struct refspec_item with either src
  17  * or dst filled out, will fill out the other such that the result is in the
  18  * "fetch" specification for the remote (note that this evaluates patterns and
  19  * returns a single result).
