I don't know either. :-)

Nitpick: There's an "i" missing in "F[i]nd" and checkdoc wants the first
sentence on the first line.

Aside from that, I think it would be useful if one could jump from the
shown inlined code into the source file, too.  Then one doesn't have to
navigate back to the filename.{c,el} link.  Maybe it could even jump to
the line corresponding to the location of point in the inlined code?  At
least the lines offset is easy to calculate.
