rmport: ready for git

- do not remove ports immediately but store them in a temporary file
  and remove them once the script has iterated over all ports to be
  removed. This prevents failed searches. The Subversion version
  used a temporary worktree so the main tree was unaffected.
- remove a "merge" from a question, we use rebase now.
- check if INDEX is readable and exit if not
