vim: mark end-of-line? trim blank lines?

I'm wondering if I can convince vim to do either of the following:
  • Display a marker for the end of line. Similar to what :set list does, but without displaying tabs and such.
  • I like the auto-indenting feature of vim, but I wonder if I can get it to trim lines to /^$/ if they match /^\s*$/?

Does anyone know?

Thanks for taking the time to read!

I did some searching around once I realized that what I really wanted was a global replace, and I just knew that vim must have macros with bindings for different states of the application, and with much persistence I was proven correct! Check it out:

autocmd BufWritePre * :%s/\s*$//
I put that in my ~/.vimrc file, and it makes me happy. It does a global replace before writing the buffer. Notice that it will do this for every file you write. If you want to only have it alter C files, for example, change the line to look like this:

autocmd BufWritePre *.c :%s/\s*$//
From what I've read, that should work fine.

Does anyone know, off the top of their head, how to make this restore the cursor position after completion? I know vi commands to do that but I don't know that I could include them in one line, or perhaps as an addendum to that regex or something.
