New submission from John Fisher:
Some characters repeated in the pattern break re.match:
Linux python 2.7.6
###################################
# test.py
import re
#diffitem = "libstdc+" succeeds

#diffitem = "libstdc**" fails

diffitem = "libstdc+\+" succeeds
line = "time 1.7-23build1"
result = re.match(diffitem, line)
print result
