Oh, what a mess...
I tried to make myself more clear, and obtained the opposite.
I know the password trick via highlighting.
I use it for my fetchmailrc files.
I don't want to hide passwords.
I just want to replace some text by another, without
changing the file. Only an apparent, visual change.
Like folding: you replace 10 lines by one,
but you are not really replacing the lines in the file.
It is just a visual trick.
What I want should be possible, since folds do exactly that.
Sorry for the mess....
Luis.
