Python's RE syntax doesn't support the < or > metachars than some engines
support.  \b (zero-width match for beginning or end of a word) achieves
something similar:

>>> re.match(r'\[Merge\b', '[Merge]')   # does match
<_sre.SRE_Match object at 0x819d838>
>>> re.match(r'\[Merge\b', '[Merged]')  # doesn't match
>>>
