Subject: [PATCH] Bug#27015 s_query.q_append() called without
 s_query.reserve()?

there is a way to miss allocation for the punctuation marks,
namely if (q == EOF) is true inside of append_identifier(), i.e in case names are not quoted
(not by default).

Replacing q_append with the method with reallocation if needed.
