Re: LESS env var and a pager

[Diggory Hardy <diggory.hardy@gmail.com>]

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.]
