I just had a look att commit 109ee5d33694a03cda3424b4846584250832ba8e.
IMO, to imitate bash behaviour isn't the right thing to do. It's a bug.
Imitate dash behaviour instead.
Refer to the test shell/ash_test/ash-misc/local1.tests.
Upon entering function `f', `local a' makes a copy of the variable
with the same name in the upper scope. `local a' should not
implicitly `unset a'. Let the user decide what to do with variable
'a' (modify, unset, whatever).
What do people think?
Cheers,
