Nah, looking at the code, it was so that sizeof() would not include
the trailing NUL.

But compare_string is just ugly.   Looking at it a bunch,
I suspect we should factor out @keyword@ expansion
into a separate function; then we could have better error
messages that gave the whole expected line.
I might send a patch in like that soon.

In the meantime, please either send a separate patch
that removes todo_space, or just leave todo_space alone for now.

I'd like to see the code that implements @todo_wine@ submitted
in the same patch as the first test that uses it.
