Inconsistant behaviour

[David E. Goldfarb <DEG at SCRC-TENEX>]

In ZWEI in Experimental System 202.21, ZMail 40.7, Experimental Tape 7.0,
Experimental LMFS 22.10, Experimental Symbolics 9.3,
Experimental Canon 10.3, microcode 855, on Boxer:

Meta-C (Capitalize word) will not abort if given an argument forcing it
beyond the end of buffer (Meta-U and Meta-L do, on the other hand beep
and abort in this case).  Instead, it will beep and retain the cursor at
its old location, but still capitalize the rest of the buffer.
