Are these compiled into the executable?

More exact: although the terminal seems wide enough, text is wrapped 
into 15?-20? char-wide column. Cause may be that text isn't redrawn if 
the terminal width is adapted within the GUI window. That only happens 
if the complete pane is moved and becomes a separate window, and then 
text is only shrinked in width when "needed", not expanded.

On MinGW the Octave executable seems to be recognized as a terminal (see 
previous thread on this). Selecting "start minimized" helps to get it 
out of the way.
A positive side effect is that in the desktop / Start Menu shortcuts, 
setting colors to black text on white background makes the Octave 
terminal black and white as well. Only primary colors work.
The other panes are not affected.


Other things (mentioned here and not (yet) in bug tracker as they seem 
MinGW build specific):

- Setting the cursor shape and blinking on/off has no effect in the 
terminal. In the editor the cursor does blink and changes shape 
depending on Ins key status

- The terminal doesn't give any output from user commands. E.g., 'printf 
("Hello\n")' gives no response, just the next prompt.
However, error messages and warnings do appear.

- quotes and double quotes are always duplicated (also on 3.6.2 MSVC 
snapshot)

- Using the fonts "Courier", "Courier New" and "DejaVU Sans Mono" the 
cursor position is way out of sync with the text (too far to the right). 
Also on MSVC 3.6.2 snapshot.
