doc/pretty-formats: describe index/time formats for %gd

peff · gitster · commit 522259dc3adf · 2016-07-22T13:47:33.000-07:00
The "reflog selector" format changes based on a series of
heuristics, and that applies equally to both stock "log -g"
output, as well as "--format=%gd". The documentation for
"%gd" doesn't cover this. Let's mention the multiple formats
and refer the user back to the "-g" section for the complete
rules.
