Re: how to make next-error work on non-grep non-compilation

No the file has no particular extension, but i can give it whatever extension 
it needs if that makes the job easier.

It should not be editable.

what should I set it to?  I'm trying to make the format of the file already 
compatible with grep.  I'm assuming that only the grep match lines are 
important and not the header lines which show the grep command line.

Well I would like the buffer to have a more generic name so that if i run my 
function many times, it reuses the same buffer, thus destroying its old 
content.  So I'd rather not make the buffer simple a file-visiting buffer.
