Re: A suggestion to add to gnu ed: command line option to start on line foo or bar.

[Matthew Polk]

I'm currently going through the source code for ed and given that
stuff like second_address is in multiple files and multiple functions,
it's a bit confusing how to do this. For anyone who knows more about
the program source code than I do, which file do you think I should be
looking into for this? With a casual glance at it, it appears that ed
just dumps the file contents into a buffer and just sets the last line
as the default. Any suggestions?
