Re: Strange `file-name-sans-extension' behavior

[Richard Stallman]

    Strictly speaking, it isn't correct even for Windows, as this
    example shows:

            c: + bar -> c:./bar, not c:/bar

I don't understand this example, partly because the two parts
are not labeled as to what they mean.  "c: + bar -> c:./bar"
could be a statement of what something actually does (what something?),
or it could be a statement of what something ought to do.
I can't tell which.
