Hi Dmitry,
Recently I worked with the old version of the patch and found a bug.
So, I think it is better to notify you immediately, so you can fix it in
rebased/revised version.
I noticed, that operator AROUND(N) works only
in case of non-negative operands. If any of the operands is negative, it
behaves as phrase operator <N>. It is caused by lack of TS_NOT_EXAC
flag and AROUND(N) operator check in function TS_phrase_execute in
branches for negated operands.
