They are identical, but they do have one advantage.. you can use / inside the rule text without having it escape it.
it makes things like http:// much more readable, as in a normal / delimited rule you'd have to write http:\/\/
The rules that use m{ likely contain many /'es in the text, so this was done for readability.
