WIP: Re-indent surfraw script in more consistent way
Previously, "surfraw" script was indented with mix of tabs and spaces, with indentation visually matching nesing of control structures only with tab stop equal to 8, that defeats whole point of tabs.
With this change, all code uses tabs for indentation; all code is aligned with spaces. Here is example:
function_f () {
case ${value} in
-foo|-bar) setoptyn frob yes;;
-q=*) setopt qq $optarg;;
*)
funcall1
funcall2
;;
esac
}
if [ -f /path/file ]
then
if [ -n "${var}" ]
then
do_something
else
do_something_else
fi
