bug#8399: 23.3; save-some-buffers ignores buffer names

[Uday S Reddy]

The save-some-buffers command queries the user as to which buffers
should be saved.  However, if the buffer has a file-name, it uses the
file-name in the dialogue instead of the buffer name.  If the buffer
name happens to differ from the buffer's file-name, this is confusing to
the users.  (It happens quite frequently in VM, which uses obscure
file-names for the caches of POP/IMAP folders, but the buffer names are
recognizable.)

The attached patch (on Emacs-23 head) modifies the dialogue so that
file-names are used in the dialogue only when they coincide with the
buffer names.  Otherwise, buffer names are used preferentially.

Cheers,
Uday
