parse_set and parse_unset: restore stomped char before returning

Browse Source 
The parsing in parse_set and parse_unset saves, overwrites with a NUL, and restores a character in the string that is being parsed.  If there is a malloc failure between overwriting and restoring, the restore is not done.  This commit changes that behaviour to restore before returning.
