# adds inline image and source code include support to default formatter (which
# does not necessarily make sense in repo2html, since it styles commit
# messages...if you try to inline an image in a commit message using this
# format, then you should probably pretend the brackets are staples and lodge
# them into your skull)
#
# XXX: These do little to prevent against malicious code execution since, well,
# they are used for my own personal content...you've been warned (they are also
# strongly bias toward allowing only Unix-like paths)
