It doesn't have a documented way for the caller to insist that the
string be quoted for a POSIX shell rather than the user's shell. In
particular, the (undocumented) mechanism that Tramp uses to get this
behavior will obviously break in the presence of (as recommended by the
documentation) an advised or completely overridden version of the
function put in place by a user who has an unusual shell.

Maybe what needs to be done is to have separate functions
shell-quote-argument-msdos, shell-quote-argument-nt,
shell-quote-argument-posix, and then have shell-quote-argument call
those based on the user's shell.
