It is often desirable to format the output to suite the output medium.

Formatted output is triggered by the value of the `ui.formatted'
configuration variable or - if it is unset - when `sys.stdout' points
to a terminal device. Please note that `ui.formatted' should be
considered an implementation detail; it is not intended for use outside
Mercurial or its extensions.
This function refers to output only; for input, see `ui.interactive()'.
This function always returns false when in plain mode, see `ui.plain()'.
