Good day, Philip!
Some days ago I send a request, but it is still no your answer. Do it please.

Hi, Philip!
PCREPARTIAL documentation says:
If there are at least two slots in the offsets vector when a partial match is
returned, the first slot is set to the offset of the earliest character that
was inspected.
Some time ago there was no PCRE_INFO_MAXLOOKBEHIND parameter in PCRE. In those
days PCRE only keeps offset of the earliest character that was inspected to
help main application to decide what part of current segment is needed to keep
(http://www.exim.org/lurker/message/20090905.102602.086262ae.en.html).
Then the influence of lookbehind assertions was discovered. Thus "the offset of the
earliest character that was inspected" can't longer satisfy. Thereat
PCRE_INFO_MAXLOOKBEHIND was born to give appropriate instrument to main application.
But another thing was not take into consideration: PCRE_INFO_MAXLOOKBEHIND is
suitable to correspond with last bumpalong offset, not with offset of the
earliest character that was inspected. The former is unsuitable now.
So I propose to return in ovector's first slot the last bumpalong offset.
PS Finding English words is very hard for me due to my bad English. Sorry if I
can't deliver my point of view clearly enough.
Thanx.
