Kevin Harwell 4b5d11ec17 func_strings: HASHKEY - negative array index can cause corruption ...

This patch makes it so only matching non-empty key names, and keys created by
the HASH function are eligible for inclusion in the comma separated string. It
also fixes a bug where it was possible to write to a negative index if the
result buffer was empty.
