This adds a support for macro_rules! keyword which declares
a macro. It also includes a test case.

Hi Konrad
Thanks for the patch, this would be a useful addition

I think you want the `!` before the `[\t ]`. We could probably get away
with just adding `macro-rules!` as another alternative in the group
starting with `struct`

We would write this sentence in imperative mood, i.e., give the codebase
the order to become so. That a test case is included can be seen from
the patch text and need not be mentioned.
In this case, if I were the only one to judge, I would accept this
commit without a message if the commit summary were:

Technically, this looks fine. Originally I thought that the new keyword
could just be thrown into the mix of struct|enum etc, but judging from
the (existing) test cases, this new case looks fairly different (I am
not a Rust expert, so I cannot really tell). Therefore, it is OK to put
it in an alternative branch in the regexp.

The above is where you write the proposed log message, not where you
write the differences between v1 and v2 (which, if exists, would be
below the three-dash line after your sign off). After all, people
who are reading the final history of the project in "git log" will
not even know or care that what they are reading is the second
iteration and/or there was a first iteration that was different from
the final version.
> Subject: [PATCH v2] userdiff: permit Rust's macro_rules! keyword in hunk headers
Somehow I find the "permit" a bit odd---it is not like we are
disallowing Rust programs written in certain way.
userdiff: recognize 'macro_rules!' as starting a Rust function block
or something?

As to the simplified rule that matches 'pub macro_rules!'.
We assume what is written by the end-user, in which these patterns
are used to find function headers, is a syntactically correct
program. This allows us to write a pattern that may match with a
syntactic nonsense (i.e. false positive is perfectly fine). What
we care about is to avoid false negatives---if our pattern does not
recognize what users would consider a valid and common function
header line, that is a problem.
So, from that point of view, you do not have to worry too much about
'pub macro_rules!' matching your pattern.

I notice that you still allow "macro_rules !" as Phillip pointed
out. Is that intended?

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.
