That's it - thank you very much. I had seen how to match and reuse chunks
in the RewriteCond, but somehow missed the ability to substitute them
in the RewriteRule. I should have known it was too useful to have
been left out.

Since I only want to substitute one argument name without knowing much
else I think this will work:
RewriteCond %{QUERY_STRING} (.*)(arg1=)(.*)
RewriteRule ^/cgi-bin/prog
http://otherhost/prog?%1newarg1=%2&uname=me&pwd=password [P,L]
(I want a proxy request to hide the password usage, not a client redirect
but either could work)
