[SLOF] [PATCH v3 1/6] terminal: Disable the terminal-write trace by default

[Thomas Huth]

The terminal-write function has a built-in trace buffer feature
which is currently always enabled. Since this is only needed
for debugging, let's disable this feature by default. It can
easily be enabled again by typing "true to twtrace-enabled?"
at the Forth prompt.
