* MAXLINE is set to a value slightly larger
* than twice the longest expected input line.
* Because of the way underlining is handled, the
* input line which is to be underlined, can almost
* triple in length. Unlike normal underlining and
* boldfacing, continuous underlining affects all
* characters in the buffer, and represents the
* worst case condition. If the distance between
* the left margin and the right margin is greater
* than about 65 characters, and continuous underlining
* is in effect, there is a high probability of buffer

* processing is handled by pushing back the expansion
* into the input buffer, the longest possible expansion
* would be MAXLINE characters. Allowing for argument
* expansion, MXMLEN was chosen slightly less than MAXLINE.
* It is assumed that most macro definitions will not
* exceed 20 characters, hence MXMDEF of 100.
