fixes segfault introduced in 0a0acb55db8d7c4dec445573f1b0528d126b9e1f 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.

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" ~

It used to be aliased to !FEATURE_SH_EXTRA_QUIET for ash,
while hush had it separate from FEATURE_SH_EXTRA_QUIET.
Bring ash in line with hush.

ash --login should read ~/.profile instead of .profile in the current
directory. I noticed it while trying to figure out why /root/.profile
is only read sometimes.

move HISTFILE=$HOME/.ash_history below reading /etc/profile,
so that /etc/profile can set $HOME. HOME can be unset when
directly invoking ash --login from init without going through
getty.
