Do not hardcode paths to the default editor/pager

Use "vi" instead of "/usr/bin/vi" and "less" instead of "/usr/bin/less".
Hardcoding absolute paths is a bad idea:

    $ uname -rsv
    Linux 3.0-ARCH #1 SMP PREEMPT Tue Aug 30 07:32:23 UTC 2011
    $ which less
    /bin/less

The "$PATH" environment variable will almost always have a better idea
of where these binaries are located.
