transpose-words on $? $@

[Dan Jacobson]

Put the cursor between
$? $@
and do transpose-words, ESC t.
Nothing much seems to happen.
Well maybe nothing should, but it doesn't feel good.

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?

You're trying to curse at Emacs?  I guess the cursor is you ;-).

    and do transpose-words, ESC t.

Maybe Emacs was angry that you cursed at it ;-).

Indeed there are no words there to transpose.

This happened in Makefile mode. Well OK, they aren't words. By the
way, in bash, one at least gets a beep and the cursor doesn't move.
