If a file is being visited in a buffer but does not exist on disk, then
tab completion in find-file will not suggest it.  For example:

- make sure there are no filenames in the current directory beginning with f.
- C-x C-f f o o RET
- C-x b RET to switch to some unrelated buffer
- C-x C-f f TAB

Expected results: although there are no files currently on disk beginning f,
I am visiting a buffer for the filename 'foo', so it should complete to 'foo'.
After all, if I type f o o RET manually then the effect is to switch to that
buffer - so it should be included as a choice in autocomplete.
