The magic 100 blames back to our chief magician, Junio:

Yup, guilty as charged.

cf. [ref]

    "%s %s %s\n" with old and new commit object name and the message
    will be "2 * len(hash_in_hex) + 4" bytes long (counting the three
    whitespaces and the terminating NUL), and Shawn's original in
    6de08ae6 ("Log ref updates to logs/refs/<ref>", 2006-05-17) actually
    computed this one as "strlen(...) + 2*40+4".

    100 was merely me being sloppier than Shawn at 8ac65937 ("Make sure
    we do not write bogus reflog entries.", 2007-01-26), preferring
    being sufficient over not wasting even a single byte.
