Real men don't use sed! (ಠ_ಠ)

Code:
$ FAKEPWD=/home/user,with,commas/tmp

$ FAKEHOME=/home/user,with,commas

$ echo ~${FAKEPWD##$FAKEHOME}

~/tmp

Just kidding of course. I hope I understood your problem correctly, but according to my simulation this seems to be working as you can see.

Edit: Almost forgot to mention, this just assumes you actually are somewhere inside $HOME, since it just crudly adds '~' to the start and cuts out $HOME....
