/*
Name
  askf_tx.cpp - formatted text implementation of askfile
Function
  Implements file dialog using text prompts.
Notes
  Only one of askf_tx.c or askf_os.c should be included in a given
  executable.  For a text-only version, include askf_tx.  For a version
  where os_askfile() provides a file dialog, use askf_os instead.

  We provide a choice of tio_askfile() implementations in the portable
  code (rather than only through the OS code) so that we can call
  the formatted text output routines in this version.  An OS-layer
  implementation could not call the formatted output routines (it would
  have to call os_printf directly), which would result in poor prompt
  formatting any time a prompt exceeded a single line of text.
