grep: don't search past the end of the searched string

'*' causes the resulting RE to match 0 or more repetitions of the preceding RE:

>>> bool(re.search('.*', ''))
>>> True

This causes an infinite loop because currently we're only checking if there was
a match without looking at where we are in the searched string.
