Well...as long as you're already looking at that mess...

I'd like to see the addition of a new mh-format function "%(printf)".

Building and customizing message parts using "%(putstr)" somewhat
works, but is seriously ugly, because %(putstr) compresses repeated
whitespace within a string and doesn't parse printf formatting such as
"\n".

A new function that simply passes it's input string to printf would be
very helpful.

Thanks,

Mark
