sh: Make return return from the closest function or dot script.

Formerly, return always returned from a function if it was called from a
function, even if there was a closer dot script. This was for compatibility
with the Bourne shell which only allowed returning from functions.

Other modern shells and POSIX return from the function or the dot script,
whichever is closest.

Git 1.8.4's rebase --continue depends on the POSIX behaviour.
