modules/git: make options passed to less(1) for diff-so-fancy configurable (#3704)

Browse source 
The `-X` prevents that screen is cleared when showing a diff that's
larger than my screen.

I.e. when running `git diff` and press `q`, the last thing I want to see
is the prompt with `git diff` and *not* the part of the diff I browsed,
to be clear

    $ git diff
    $ <cursor>

Considering that this is somewhat opinionated, I decided to build an
option which allows you to pass arbitrary commands to the less
invocation.
