#18 display long string

[Ted Williams]

The lisp expression (display msg)  will return true with no display output if msg exceeds _FSmartbase_MAXBUFFERLEN bytes (about 512,000 bytes).  It should either try harder to get the necessary space or it should return an error.
Recreate: Create a msg that exceeds 512K bytes. Then attempt to display msg as noted above. Note that only true is returned (msg is not displayed
Notes:  1. If there is a lot of memory available, it should be pressed into service as this memory is returned as soon as the message is displayed.
2. The current documentation is quiet on this issue.  It should include any restrictions imposed on the string length.
