    giscanner: use re.match() instead of re.search()
    
    From Python's documentation:
    Python offers two different primitive operations based on
    regular expressions: match checks for a match only at the
    beginning of the string, while search checks for a match
    anywhere in the string (this is what Perl does by default).
    
    The different behavior between match() and search() doesn't
    matter in our case and conceptually we are checking if a
    piece of text matches a certain pattern, so match() is a
    better fit.
