Change header contents (current directory listing)

[godalming123]

Description

Hi, in my current directory list I have /home/whatever this is unecersarry and gets chopped off the screen so I would like a feature to instead print ~/this could be done by having an option to replace the start if it matches so I could say:

/home/whatever -> ~
/home/whatever/nixDots -> nixDots
/root -> ROOT:

You should also use the longer completion if two are available
