2015-05-13ash: consider "local -" case while iterating over local variables in mklocal.Eugene Rudoy
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.

2015-03-22ash: do not split the result of tilde expansionRon Yorston
