userdiff: support Rust macros
Changes since v1:
* Changed macro_rules! to be considered to use the same rule as rest of
keywords to reduce the size of a change as suggested by Phillip Wood.
This means that 'pub macro_rules!` (a syntax error) is considered to
be a hunk header.
* Written commit message in imperative mood as suggested by Johannes
Sixt.
Changes since v2:
* Updated the commit message as suggested by Junio C Hamano.
* Removed handling for 'macro_rules !' with a space in-between tokens.
While it is allowed by the compiler to have a space between
'macro_rules' and '!' it's pretty much never done.
