Just a small point here:

Well, unless I'm missing something, shouldn't the tilde above be
expanded by the shell before actually being passed as argument?

Maybe.  Some shells do and some don't:

$ echo foo=~/foo
foo=~/foo

bash$ echo foo=~/foo
foo=/home/torek/foo

for instance.

So I actually did my homework and skimmed through the relevant RFCs
(RFC952 and RFC1123); as it turns out, no, it cannot
– only ASCII alphanumerics, '-' and '.' are valid characters.

Right: tilde and slash are both verboten. (Underscore is too, but
that one does get used and some programs allow it.)
