*sigh* the code worked wih gnu sed.
BSD sed is a whole lot more finicky with regard to whitespace. And, it
appears that I've got some bug reports to file.
Anyway, this is tested on FBSD 7.2:
copy _exactly_, making sure there is no trailing white-space on any line.
Then substitute an actual formfeed char for the {CTL-L}.
FreeBSD sed does not recognize either '\n' or '\f' in the substitution
string -- it strips the '\' and outputs the printable character. *sigh*
#!/bin/sh
sed -e '
:l
/^[*][*]*$/ N
/\n..*$/ P
/\n..*$/ {
s/^.*\n//
b l
}
/\n$/ N
/\n\n[^*][^*]*$/ {
P
s/^.*\n//
P
s/^.*\n//
b l
}
/\n\n[*]*$/ s/\n\n/\
{CTL-L}/'
