bug#9796: 24.0.90; Mayor mode selection after "save as"

[Dani Moncayo]

>From "emacs -Q":

1. Create a new buffer and write something into it.
2. Type "C-x C-s" and save the buffer as "test.txt".
3. Now Type "C-x C-w" and save another copy as "test.sql".

The mayor mode chosen for the "test.sql" buffer is "SQL", whereas the
one chosen when I kill all buffers and visit the "test.sql" file is
"SQL[ANSI]".  I expected that the chosen mode was the same in both
cases.
