[PATCH v2 0/4] refspec: treat 'fetch' as a Boolean value

Here's a small reroll that cleans up some wording in the first patch, and drops the accidental inclusion of a stray 'git-diff-pairs' binary that was sitting in my working tree at the time of writing the initial commit.

Otherwise the series is unchanged, but a range-diff is attached nonetheless. Thanks for reviewing :-).

         But these values are treated as a Boolean, and stored in a struct field
         called 'fetch'. So the following:

         Since this value is truly a Boolean and will only ever take on a value
