patch - shorten ':scriptnames' and ':breaklist' filenames

[Jean-Rene David]

Here is a small patch addressing todo item:

7   Output for ":scriptnames" and ":breaklist" should shorten the file names:
    use "~/" when possible.

This is from the 'small problems' list.

I used home_replace() along with NameBuff to compact $HOME to "~/".

HTH,
