BF+ENH: added %m-%d-%Y pattern + do not add %Y for Feb 29 fix if already present in the pattern

although %m-%d-%Y is ambioius with %d-%m-%Y it comes after so it should not
be too dangerous (i.e. in upcoming days having smth like 02-01 should work as before matching
first one first) and proper fix to select between the two should follow some time
soon
