"cabal haddock" should accept --hyperlink-sources (not just --hyperlink-source)

[SamB]

I don't know how many times I've tried to pass it in the plural... it's getting annoying.

What would the best way to get this to work be?

Pretty easy. See for example the way we allow different spellings of "optimisation" vs "optimization":

From Distribution/Simple/Setup.hs:

  noArg (Flag NoOptimisation) []
        ("disable-optimization": case showOrParseArgs of
              -- Allow British English spelling:
              ShowArgs -> []; ParseArgs -> ["disable-optimisation"])
        "Build without optimization"

I'd like to make it even easier in future. Just declare flags with a single current name and a list of allowed deprecated or alias names. The latter would not show up in the --help output.

Thanks! Patch applied.

  * --help shows first long option and added --hyperlink-sources
  The --help option output now prints only the first (if any)
  long option. Because of this, --{enable,disable}-optimisation
  (british spelling) is simply added to the list of options
  without testing showOrParseArgs. --hyperlink-sources is now
  also accepted for the haddock command.
