You're right, of course.  I had changed bash a while back to be more like
ksh-86, which expanded tildes after colons when doing tilde expansion, but
have since backed that change out after deciding it wasn't Posix compliant. 
(The ksh book says ksh88 doesn't expand tildes after colons, but I have no
way to check that.)

It might be better to expand tildes after colons, but bash is doing exactly
what the documentation says it does.
