We seem to match url schemes case-sensitively: $ git clone SSH://example.com/repo.git Cloning into 'repo'... fatal: Unable to find remote helper for 'SSH' whereas rfc3986 is clear that the scheme portion is case-insensitive. We probably ought to match at least our internal ones with strcasecmp. Possibly we should also normalize external helpers (so "FOO://bar" would always call git-remote-foo, never git-remote-FOO). We could probably also give an advise() message in the above output, suggesting that the problem is likely one of: 1. They misspelled the scheme. 2. They need to install the appropriate helper. This may be a good topic for somebody looking for low-hanging fruit to get involved in development (I'd maybe call it a #leftoverbits, but since I didn't start on it, I'm not sure if it counts as "left over" ;)). -Peff
