#158: Incorrect mapping of ncurses C string-retrieval functions to Scheme
procedures

 Reporter:  nsantos     |       Owner:  felix
     Type:  defect      |      Status:  new  
 Priority:  major       |   Milestone:  4.4.0
Component:  extensions  |     Version:  4.3.x
 Keywords:  ncurses     |  
------------------------+---------------------------------------------------
 There's a bunch of ncurses functions that aren't properly mapped to
 Scheme-y equivalents.  All of the ones I've stumbled upon related to
 retrieving input strings.  To wit:

  - `(getnstr STRING)`
  - `(getstr STRING)`
  - `(mvgetnstr INT INT STRING INT)`
  - `(mvgetstr INT INT STRING)`
  - `(mvwgetnstr WINDOW INT INT STRING INT)`
  - `(mvwgetstr WINDOW INT INT STRING)`
  - `(wgetnstr WINDOW STRING INT)`

 The bug is that, as with their C counterparts, the Scheme procedures
 expect a STRING argument.  The C functions expect to be able to use said
 argument as a pointer to the retrieved string.

 The Scheme mappings should instead return the retrieved string.
