curaga:
Let's go with the filetool patch, given Greg's web use.

Hi Greg Erskine

If you add an escape character into the output it would be really bad for displaying via a web page. ...

I had no idea anyone used this for a web page. I suppose I could have printed a  space  followed by a  backspace:

--- Code: ---printf(" \b");
--- End code ---
Since the  backspace  moves the cursor back 1 position the trailing  space  would simply get overwritten if more text were added.
If the next character was a  newline,  it would print the trailing space which wouldn't be visible anyway. This was the mechanism
that made the trailing slash visible.

Hi, Rich!
Sorry for offtopic. Can you kindly explain to the newbie such a size difference?
Not a first mentioning of TC4 at the forum as the kind of milestone. What have changed later? Some kernel bloat?

I honestly don't know why the executable is so much larger. My guess is the current compiler has some "enhancements" not present
in the TC4 version that add some overhead. There appear to be some differences in how they were built.
