Unfortunately using F without X results in output no longer than one screen not being displayed, since less immediately exits and anything less would display is immediately cleared from the screen (so it just looks like the git command had no output).

I looked through less's man page and didn't find any solution other than also not specifying F, which is not so desirable since it's always necessary to press 'q' to exit less and previous output is not visible on the terminal.

[So don't follow my first suggestion.]
