Re: compile: don't ask over and over about saving unrelated files

[Richard Stallman]

    Perhaps we could make compile (actually save-some-buffers, which compile
    calls for this purpose) distinguish Y from y and N from n, for the
    purpose of remembering which files should be saved or not in the future
    without asking.

I really dislike the idea of saving certain files without asking;
however, the feature of making some files as "don't ask" for M-x
compile seems useful.  If you'd like to add that, please do.

One complication is that compile just calls save-some-buffers.
So this feature has to be in save-some-buffers, but only when it
is being done on behalf of compile, not all the time.
