Since none of those characters have word syntax, it seems right --
although why then is point moved from before the second `$' to before
the `@'?

But in Shell-script mode (which I suspect is where that text occurs),
one might expect C-M-t to work because there the `?' and the `@' are
fontified and displayed using font-lock-variable-name-face.  Should
font-lock set the syntax-table property for such characters?  If it did,
and parse-sexp-lookup-properties were set, then the transpose commands
would work as expected, right?
