           Summary: `dmd -transition=?` needs quoting => make it
                    `-transition=help`
           Product: D
           Version: D2
          Hardware: x86
                OS: All
            Status: NEW
          Severity: normal
          Priority: P1
         Component: dmd

          Reporter: timothee.cour2 at gmail.com

this flag was just introduced (in beta) ; it's the *only* flag that requires
quoting on a shell. Please use anything else than something that requires
quoting. `eg: -transition=help` 
more searchable (in code), easier to enter in shell, especially in more complex
scenario.
IIRC standard compilers (gcc, clang etc) don't do that.
