Hello,
Repeat-By:
$ shopt -s dotglob extglob
$ echo !(.foo)
. .. .other files
The doc says: "The filenames '.' and '..' must always be matched explicitly, even if
dotglob is set."
When dotglob is enabled, the shell's pattern matcher interprets an extglob
pattern beginning with a literal `.' as specifying that files beginning
with a `.' should match, so the negated pattern matches `.' and `..'.
Also the pattern !(.foo) didn't match . and .. before version 4.3.0.
This is behavior that changed more than ten years ago.
There was a relevant discussion back in January:
