Philippe Antoine 4ec90bd227 detect: absent keyword to test absence of sticky buffer
Ticket: 2224

It takes an argument to match only if the buffer is absent,
or it can still match if the buffer is present, but we test
the absence of some content.

For multi buffers, absent matches if there are 0 buffers.

For file keywords, absent matches if there is no file.
