Re: [PATCH v5 0/3] interactive git clean

Jiang Xin [off-list ref] writes:

The interactive git clean combines `git clean -n` and `git clean -f`
together to do safe cleaning, and has more features.

First it displays what would be removed in columns (so that you can
see them all in one screen). The user must confirm before actually
cleaning.

    WARNING: The following items will be removed permanently. Press "y"
    WARNING: to start cleaning, and press "n" to abort the cleaning.
    WARNING: You can also enter the "edit" mode, and select items
    WARNING: to be excluded from the cleaning.

      What would be removed...    What would be removed...
      What would be removed...    What would be removed...

To a user who explicitly _asked_ to run the interactive mode, I find
these four warning lines that shout at the user in all caps way
overkill.  I would have expected the output to begin with a line to
explain what it is listing (e.g. "Cleaning the following files:"),
the list and then

    Remove (Yes/no/edit/?) ?

The existing "add -p" prompt uses this trick to hint the user that a
further help is available by typing "?", and it is a good example to
follow.
