_? in gvim always calls IDoc("...", -1)

[MSch]

I fixed the bug by changing line 520 of haskell_doc.vim from

let i = index(keylist,key)

to

let i = index(keys,key)

Thanks for the report. The fix was slightly more complicated, as there were several use cases, other features interfering, and awkward code logic:

  haskell_doc.vim: fix ticket #5 - it turns out that the 04/04/ fix of _? fixed 
                    one use case while breaking another; the logic there was getting
                    too complicated and fragile; now somewhat straightened out (no
                    more indirection via IDoc, no more separate indices for keys with
                    or without namespace tag, simplified conditions, comments clarify
                    what should happen when, ..); tested with qualified/unqualified
                    items, qualified/qualfied as/unqualified imports, imported and
                    non-imported items; please test _? and report any issues with 
                    the rewritten code
