MFC r300683:
libc: regexec(3) adjustment.
Change the behavior of when REG_STARTEND is combined with REG_NOTBOL.
From the original posting[1]:
"Enable the assumption that pmatch[0].rm_so is a continuation offset
to a string and allows us to do a proper assessment of the character
in regards to it's word position ('^' or '\<'), without risking going
into unallocated memory."
This change makes us similar to how glibc handles REG_STARTEND |
REG_NOTBOL, and is closely related to a soon-to-land fix to sed.
Special thanks to Martijn van Duren and Ingo Schwarze for working
out some consistent behaviour.
