Re: command for creating local variables in files

[Richard Stallman]

    So for a file-make-local-variable command we need questions like

      Major mode: (default <the current major mode>)
        ...
      Variable:
        foo...
      Variable foo set to:
        ...

You are describing a command to set up an entire local variables list.
That's not what file-make-local-variable should do.  That command
should add or alter ONE variable in the local variables list; only
one.  It can read a variable name and the value string in the usual
way with the minibuffer.
