patch 9.1.0217: regexp: verymagic cannot match before/after a mark
Problem: regexp: verymagic cannot match before/after a mark
Solution: Correctly check for the very magic check (Julio B)
Fix regexp parser for %>'m and %<'m
Currently %'m works fine, but it is unable to match before or after
the position of mark m.
closes: #14309
