It turned out that it was not a good idea to line break AC_MSG_* 
functions. :-( I didn't verify that properly before; my bad.

Here's a new-new review which restores the old long (but 
properly-looking) AC_MSG lines.

(If you're curious, the line break was printed verbatim. Putting a 
trailing \ did remove the line break, but then the indentation level 
showed up as verbatim spaces in the output.)
