ash: consider "local -" case while iterating over local variables in mklocal.
...
fixes segfault introduced in 0a0acb55db
with functions using "local -".
test-case: f() { local -; local x; }; f
note: with this change applied multiple 'local -'s still cause multiple entries to be added to the localvars list.
this problem will be addressed in a separate commit.

ash: do not split the result of tilde expansion
...
A tilde expansion generates a valid pathname. Splitting it using IFS
either leaves it unchanged or changes it to something unintended.
Example:
IFS=m HOME=/tmp; printf "%s\n" ~
