M-x compile *Help* choices don't give new recruits firm feeling

[Dan Jacobson]

Gentlemen, shall we examine *Help* seen upon saving files in M-x compile:
Type SPC or `y' to save the current buffer;
DEL or `n' to skip the current buffer;
RET or `q' to exit (skip all remaining buffers);
! to save all remaining buffers;
ESC or `q' to exit;
^R to display the current buffer;
or . (period) to save the current buffer and exit.

Firstly, it is not clear if exit means:
go ahead and compile, or
stop just like C-g (which should be mentioned too, like it or not)

Furthermore, q is mentioned twice.

P.S. the ^R above was a raw ^R until Gnus warned me upon sending this.
Therefore put "C-r" into the *Help* buffer instead.
