Made it work like this:

upcase-previous () {
    zle backward-word
    zle up-case-word
}

zle -N upcase-previous

bindkey Ē upcase-previous

Ē is the key the VT sends on <M-caps>, which puts Emacs
in caps-mode - so here, I can use the same key to
upcase the last word - it is not as good as in Emacs,
because for a split second you see the "incorrect"
filename, and you type it, and that might bite you
later if you do it too much - but still sort of
cool. Wow, I'm certainly happy I had this discussion
with you, otherwise I wouldn't have thought of looking
this up.
