It says: --- An initial =E2=80=98~/=E2=80=99 expands to your home directory. An initial =E2=80=98~USER/=E2=80=99 expands to USER=E2=80=99s home director= y. --- Assuming the "An initial" refers to the first parameter, then (expand-file-name "~/" "/tmp/") =3D> "/home/larsi/" works as advertised, but (expand-file-name "~" "/tmp/") =3D> "/home/larsi" is a different thing: "~" is a perfectly valid file name, so having this function map that to something else is just... wrong. (expand-file-name "~larsi" "/tmp/") =3D> "/home/larsi" is the same: Also wrong and undocumented. The doc string continues with further confusion: --- See also the function =E2=80=98substitute-in-file-name=E2=80=99. --- See it for... what? For further expansions this function is going to do? Fortunately not: (expand-file-name "$HOME" "/tmp/") =3D> "/tmp/$HOME" So that's probably just meant as "that's also a function that does file name stuff, but it has nothing to do with this ~ thing we just discussed"? So what to do here? I think the current, undocumented (expand-file-name "~" "/tmp/") =3D> "/home/larsi" must surely be an error, and that should be fixed instead of the callers?
