Hi Mark,

Thanks for your review! I've implemented all your review comments, and
have attached a new patch.

I sidestepped this by putting the new sentence on a new line. This is
also what I do with all the manpages I write. :-D

+SRFI-28 provides a basic @code{format} procedure that provides only
+the @code{~a}, @code{~s}, @code{~%}, and @code{~~} format specifiers.
+You can import this procedure by using:
+(use-modules (srfi srfi-28))
address@hidden lisp
address@hidden {Scheme Procedure} format message arg @dots{}
+Returns a formatted message, using @var{message} as the format string,
+which can contain the following format specifiers:
address@hidden @code
address@hidden ~a
+Insert the textual representation of the next @var{arg}, as if printed
+by @code{display}.
address@hidden ~s
+Insert the textual representation of the next @var{arg}, as if printed
+by @code{write}.
address@hidden ~%
+Insert a newline.
address@hidden ~~
+Insert a tilde.
address@hidden table
+This procedure is the same as calling @code{simple-format} (@pxref{Writing})
+with @code{#f} as the destination.
