git-sh-i18n: restructure the logic to compute gettext.sh scheme
Instead of having a single long and complex chain of commands to decide what to do and carry out the decision, split the code so that we first decide which scheme to use, and in the second section define what exactly is done by the chosen scheme. It makes the code much easier to follow and update. Signed-off-by: Junio C Hamano <gitster@pobox.com>
