Display text-based waitbar/progress bar.
This function is similar to the waitbar function but is a text, rather
than graphical bar. The waitbar is filled to fraction frac which must
be in the range [0, 1]. Values exactly equal to 0 or 1 clear the waitbar.
The optional message msg sets the waitbar caption. If Octave is running
in a smart terminal, the width is automatically detected, and msg is
displayed in the waitbar (and truncated if it is too long). Otherwise,
msg is not displayed and the width is initialized to a default of 50
characters, or it can be set to n characters with
text_waitbar (0, n). If no terminal is detected (such as when
Octave is run in batch mode and output is redirected), no output is
generated.
Additional arguments are ignored for compatibility with the graphical counterpart of this function but there are no guarantees of perfect compatibility.
