macro implementation notes

#+macro: version 1.0

We have the application running version {{{version}}}.
Notice that it has to be within 3 brackets and no internal spaces.

#+macro: greet Hi $1, how is it going?

Now let's try saying hi: {{{greet(Wally)}}}.

#+macro: greetreply {{{greet($1)}}} - *$1* :: $2

Now let's metagreet: {{{greetreply(Wally, it's going good)}}}

One complain is about multiline macros, though it could be complicated
since the notion of how to implement multiline varies upon
context. For html export that would mean =<br />= but in plain text it
could just be line break.
