Build tags misplaced in some files about goncurses HOT 4 CLOSED

Thanks for the patch. I should have it pushed to tip in a couple days. Were you 
able to build the complete library on OSX? If so, I may remove the build tags 
entirely as that was the only reason I added build tags at all.

I was, yes.  However, it looks as though it used ncurses from MacPorts.  No 
idea if it installs cleanly on a clean install, but frankly I'd just document 
"you need ncurses, confirmed to work with 5.9.20110404 from MacPorts".

% hg pull -u

% go install -v

I still haven't gotten around to _testing_ it.

go version go1.1.2 darwin/amd64

Xcode 4.6.3

% port installed ncurses
The following ports are currently installed:
  ncurses @5.9_2 (active)

I've removed the build tags entirely for now and see what bugs, if any, crop up 
for Mac users. Some users reported issues with MacPorts but that was a while 
ago and maybe they've been resolved. I'll make the doc changes and update the 
front page.

Fix pushed to tip and changes made to documentation.
