X/* There is some ugly code here, since I assume that code looking
X at the input a character at a time is very time-critical.
X Action functions are called with the start of the text to process,
X and return a pointer to where they left off.
X When an action function hits the end of the string,
X it returns NULL and sets the action pointer to the function to
X call next (often itself), or to NULL for the default.
X A non-NULL return implies that the default action function must
X be called next and the action pointer is irrelevant.
X Remember that the general form of most ANSI escape sequences is
X ESC [ <n1> ; <n2> ; ... <c>
X where <c> is the command code and <n1>, <n2> etc. are optional
X numerical parameters.
