Log Message:
-----------
Eliminate some no-longer-needed workarounds for palloc's old behavior
of rejecting palloc(0). Also, tweak like_selectivity() to avoid assuming
the presented pattern is nonempty; although that assumption is valid,
it doesn't really help much, and the new coding is more correct anyway
since it properly handles redundant wildcards. In combination these
changes should eliminate a Coverity warning noted by Martijn.
