Bug with utf8 chars

[Mark Peek]

Anton Yuzhaninov just reported this bug after tcsh 6.15 was imported into FreeBSD:

 > In tcsh 6.14.00 this alias (which useful under screen) work fine:
 >
 > alias postcmd 'echo -n "\033k\!#:q\033\\"'
 >
 > But under tcsh 6.15.00 it segfault.

I don't have time to look into this right now from work but it appears to fail 
the same way on Linux (CentOS 4.4) as well.
