Is it worth mentioning in the commit message that this includes a
const-correctness tweak?

Pre-existing, but per RFC 3986, we should probably be using strcasecmp
for scheme comparisons (I'm not sure if g_uri_parse guarantees a
lower-case return, even when the user passed in upper case).  That can
be a separate patch.
