>Description:

m4 'changequote' macro doesn't understand multicharacter symbols
for quotes. That is, 
   changequote(<<,>> 
works identically as
   changequote(<,>)
whereas man m5 says:
       changequote     Defines the quote symbols to be the first and 
                       second arguments.  The symbols may be up to five
                       characters long .

>How-To-Repeat:

This command line and program output illustrate the bug:
===============================================
$ echo 'changequote(<<,>>) <<quoted text>>'|m4
 <quoted text>
===============================================
no angle brackets should appear in output,
because double angle brackets must be considered
quotation symbols


>Fix:
	
a) include this problem to BUGS section for 'man m4'
b) just fix m4 sources
