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

I think the file-name is only useful when you have buffer "file",
"file<2>", "file<3>", ... so your check is going in the right direction
but it should also use file-name when the buffer name matches
(concat "\\<" (regexp-quote (file-name-nondirectory buffer-file-name))
"<[0-9]+>\\'"), and it should never use file-names when uniquify
is used.
IMNSHO,
