As someone already pointed out,
we have make-buffer-file-executable-if-script-p and I recommend everybody
add it to his after-save-hook.

As for making all sh-script mode buffer executable, I strongly
oppose this idea, since many script files are never meant to be executed,
but only sourced (this is the case for .bashrc kind of things for example,
but also for many other files when you write an extensive script and
split it into modules/libraries/...).

Another reason why I oppose this idea is because the after-save-hook
setting above is a much better solution which also covers awk scripts,
prl scripts, foo scripts, bar scripts, ...
