+1 to the general concept of keeping the Unix API unchanged.
However, this specific solution doesn't allow Windows users to use
"foo*bar" patterns (= embedded asterisks).

I'm concerned about API divergence between Windows and Unix. Could we
try to minimise the possibilities for Windows admins to write code (say,
Python code using subprocess.check_call()) that won't work on Unix, and
For example, how about if we only perform the substitution you describe
if the pattern had a magic prefix, so «--search "nostar:foo#bar%"» would
pass "foo*bar?" to the API's on *all* platforms? This way, Windows code
would work on Unix, and Unix code that actually searches for percent signs
would work on Windows.
