Git accepts dates/times in a flexible but very specific form. I can
never quite remember what the rules for this are and reading the source
code is rather more helpful than the documentation for understanding.
git rev-parse --since= can be used to verify how things are interpreted.
This adds handling for it to the completion. It will use _dates if
you start with "20" for the year. A description passed to the
function is still used with compadd -x so, e.g. after git gc --prune=
the list will start with the description "date [2 weeks ago]" before
breaking it down into months, weekdays etc. The word "ago" is widely
used in examples in git documentation but absent from the completion
because it is simply ignored and does nothing.
"approxidate" is the term git uses even in the documentation. Some
options take other formats.
