Remove useless character-length checks in contrib/ltree.
The t_iseq() macro does not need to be guarded by a character
length check (at least when the comparison value is an ASCII
character, as its documentation requires). Some portions of
contrib/ltree hadn't read that memo, so simplify them.
The last change in gettoken_query,
- else if (charlen == 1 && !t_iseq(state->buf, ' '))
+ else if (!t_iseq(state->buf, ' '))
looks like it's actually a bug fix: I doubt that the intention
was to silently ignore multibyte characters as if they were
whitespace. I'm not tempted to back-patch though, because this
will have the effect of tightening what is allowed in ltxtquery
strings.
