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