add -F and -X to default $LESS environment variable (#6611)
The option '-F' causes 'less' to automatically quit if the contents fit
the screen and the option '-X' causes 'less' to not clear the screen after
quit. I think both options are generally useful for terminal applications.
They are in particular useful for Git as it runs all output through a
pager. Git will run 'less' with '-FRX' by default if the environment
variable $LESS is not defined [1]. Since oh-my-zsh used to set $LESS to
'-R', Git would not override this setting. Consequently, Git would
display even a single line of output in a pager and the user would need
to explicitly quit that pager (see mailing list discussion [2]).
Therefore, lets change the oh-my-zsh default value for $LESS to '-FRX'.
This would be useful for oh-my-zsh Git users and likely for users of
other applications that use 'less' too.
