In Lua patterns, the minus is a non-greedy version of the "*".

You can escape it with % => "Max%-Forwards", but in your case, since
you're looking for a plain string, you can use the "plain" option of
string.find:

offset = string.find(msg, "Max-Forwards", 1, true) -- subject, needle,
start position, plain?
