This only works for options of type --longoption=something, and not for
options of type -shortoption something. But since every short option in
latexdiff has a corresponding long option, this should still allows the
user to pass every possible options.
For instance to call
latexdiff -c FLOATENV=foo,ARRENV=bar
use
git-latexdiff --config="FLOATENV=foo,ARRENV=bar"
The implementation has the side effect of allowing
git-latexdiff -- OLD
to be similar to
git-latexdiff OLD --
Moreover it uses an array to store the options to latexdiff so we switch
from sh to bash.
