[xmonad] Partial match in prompt

[Владимир Сидоренко]

Yes, thank you.

Now i have new problem. maybe it's even a bug.
If I define prompt in this way:

data Songs = Songs
instance XPrompt Songs where
    showXPrompt Songs  = "Song: "

songsPrompt :: XPConfig -> X ()
songsPrompt c = do
    cmds <- io $ getSongs
    mkXPrompt Songs c (mkComplFunFromList' cmds) (\s -> spawn "mpc play")

getSongs = return ["Nigthwish - 1", "Nightwish - 2"]

(Notice song names)

Then i call this prompt and hit <tab> twice to select second "song", and i
get this in prompt:
"Song: Nightwish - Nightwish - 1"
if i hit tab more, i get:
"Song: Nightwish - Nightwish - Nightwish - Nightwish - 1"

But if remove spaces:
getSongs = return ["Nigthwish-1", "Nightwish-2"]
Everything works fine.

This behaviour is made on purpose? Or it's my mistake somewhere? )

Thank you.
