vim-patch:9.1.0217: regexp: verymagic cannot match before/after a mark (#28074)

Browse Source 
Problem:  regexp: verymagic cannot match before/after a mark
Solution: Correctly check for the very magic check (Julio B)

Fix regexp parser for \v%>'m and \v%<'m
Currently \v%'m works fine, but it is unable to match before or after
the position of mark m.
