[issue20810] literal re fails to match

[Jonathan Epstein]

New submission from Jonathan Epstein:

All 3 of these regex's should match, but in practice only m2 does.  Found deep 
in the bowels of debugging a larger problem.


import re

mainProjectsPath = '/groups/larvalolympiad/larvalolympiad/Projects/'

m1 = re.match('larvalolympiad',mainProjectsPath)
m2 = re.match('.*larvalolympiad.*',mainProjectsPath)
m3 = re.match('/larvalolympiad/',mainProjectsPath)

print(m1)
print(m2)
print(m3)
