Fix lquery's behavior for consecutive '*' items.
Something like "*{2}.*{3}" should presumably mean the same as
"*{5}", but it didn't. Improve that.
Get rid of an undocumented and remarkably ugly (though not, as far as
I can tell, actually unsafe) static variable in favor of passing more
arguments to checkCond().
Reverse-engineer some commentary. This function, like all of ltree,
is still far short of what I would consider the minimum acceptable
level of internal documentation, but at least now it has more than
zero comments.
Although this certainly seems like a bug fix, people might not
thank us for changing query behavior in stable branches, so
no back-patch.
Nikita Glukhov, with cosmetic improvements by me
