As Gregory Neil Shapiro <gshapiro@gshapiro.net> reminded me, this was fixed 
(after 4.3 was released) with this change: 

revision 1.10.2.2 
date: 2001/05/24 20:52:13;  author: gshapiro;  state: Exp;  lines: +9 -9 
MFC: String operations could silently truncate long strings, leaving the output 
corrupted.  Mark's patch fixes this be removing the MAXTOK limitation on 
substring operations and allowing the putback buffer size to be the 
limiting factor.  If the putback buffer size if reached, m4 gives an 
error instead of silently truncating the string.
