Some flags have not been recognized: prompt-cont

When running it on Windows 10 and lts-5.2 I got:

Some flags have not been recognized: prompt-cont,

Well, it spews warnings, but it should still work, right? There's a bit of a setup that ide-haskell-repl has to do in order to parse GHCI's output:

ide-haskell-repl/src/ghci.ts

Lines 50 to 52 in c1cd88c

	`:set prompt2 \"\"${EOL}` +
	`:set prompt-cont \"\"${EOL}` +
	`:set prompt \"\\n#~IDEHASKELLREPL~%s~#\\n\"${EOL}`,

prompt-cont has been added in GHC 8.2 I think, so earlier versions show warnings and ignore it. I didn't think checking GHC version is required in this case, since it doesn't directly affect functionality.

Yes, it's only a warning

@varosi Would it be possible to fix this warning using a conditional based on GHC version?

@razvan-panda Yes, but it is on plug-ins side.
