Hold Space

Heading translation in `sed`

This still has some problems

If the last two lines of the input are a heading, they get eaten

Why?

        /^\(.\)\1\1*$/ { x; 
                         y/abcdefghijklmnopqrstuvwxyz/ABCDEFGHIJKLMNOPQRSTUVWXYZ/;
                                      x; d;
                       }

This uppercases the hold space

but d skips the print and starts prcessing the next line of input

        $ { p;x; }

So the special last-line behavior is skipped

I tried hard to fix this, but I'm not clever enough
