Adding a new option, e.g., "--rfc-lowercase", to support such need every time somebody wants to use different strings would lead to insanity of accumulating unbounded number of such options. Allow an optional value specified for the option, so that users can use "--rfc=3Drfc" (think of "--rfc" without value as a short-hand for "--rfc=3DRFC") if they wanted to. This can of course be (ab)used to make the prefix "[WIP PATCH]" by passing "--rfc=3DWIP". Passing an empty string, i.e., "--rfc=3D", is the same as "--no-rfc" to override an option given earlier on the same command line.
