I have a few questions about programming in Emacs Lisp. I hope you can help. Here they are: 1. Is this a good place to ask questions about programming in Emacs Lisp, especially with regards to text processing? If there's a better place, I'd appreciate knowing. 2. I want to write an interactive Elisp program to remove sequential duplicate lines from a buffer. This buffer is not sorted, and it should not be sorted. The program should simply look for two sequential lines that are identical, delete one, and then move on to the next line and do it over until it reaches the end of the buffer. BUT, I do not want the answer to this problem (i.e., I don't want an Elisp answer) ... I want hints on how to program it. I want to learn the answer myself, if possible. Any ideas or pointers?
