I thought these patterns were matching absolute filenames, in which case I
am not sure what "no leading directories" could mean (at least on GNU).

Sorry, I was unclear: I meant that there doesn't seem to be special support
for MS-DOS and Windows filenames elsewhere *in auto-mode-alist* (as I put
it above, "in this default value"). If "_emacs" is to be supported, surely
other similar patterns should be added for other dot files? (The same
applies to "c:.emacs"; but again, that's not an absolute filename, which
would be "c:\.emacs".)
