There's no reason why you couldn't do a C REPL, so having the framework for it in llvm.org seems reasonable. Just the generic part is enough trickery it is worth sharing.
I'm not sure why you care about the fact that Repl.h includes something from Command, but if you do then probably the easiest way to sort that out is to move REPL.h and REPL.cpp into Commands. The REPL is really a modification of the expr command anyway (you can access it at any time in a swift debug session by "expr --repl -- " and the interactive REPL just does some setup and runs lldb expressions in the repl mode. So even though it is a feature of expressions, and the actual implementation of the REPL is properly somewhere in the Swift tree, it would be equally valid to consider the generic REPL code an extension of the CommandObjectExpression, so living in Commands and #including "CommandObjectExpression" seem reasonable.
