* A struct refspec_item holds the parsed interpretation of a refspec. If it

|
|
* (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 "".
