At first I wrote it in sed:
----------8<----------8<----------8<----------8<----------8<----------
: top
s/\(\n.*\)\n\(.\)^H\2/\1\2\
/
t top
s/\(.\)^H\1/\
\1\
/
t top
s/\n\([^\n]*\)\n/${bold}\1${endbold}/g
----------8<----------8<----------8<----------8<----------8<----------
Then I ran s2p on the script -> wrong perl script! ('\n' is handled
incorrectly.) A rewrite in perl:
----------8<----------8<----------8<----------8<----------8<----------
#!/usr/local/bin/perl
eval "exec /usr/local/bin/perl -S $0 $*"
if $running_under_some_shell;
$SO = "\033[7m";
$SE = "\033[m";
line: while (<>) {
while (1) {
while (s/(\n.*)\n(.)\010\2/$1$2\n/) {
;
}
last if !s/(.)\010\1/\n$1\n/;
}
s/\n(.*)\n/$SO$1$SE/g;
print;
}
