`nimble develop https://github.com/ba0f3/scram.nim` doesn't strip extension; nimble develop scram strips extension
oftentimes nimble packages start out using just a url so installation is `nimble develop https://github.com/ba0f3/scram.nim`  ; this installs to scram.nim  (actuall ba0f3/scram.nim but that's a separate issue covered in https://github.com/nim-lang/nimble/issues/577)

then when they get published to nimble packages, preferred installation becomes `nimble develop scram` ; this installs to scram instead of scram.nim
this is inconsistent (scram vs scram.nim)
