It seems what is desired is a variable that toggles globbing between one of
two behaviors:

The result of a globbing operation that fails causes the shell to return
the filename substitution pattern, rather than an error, if the pattern
is not matched, i.e.

sh> echo *.d
*.d
sh>

*or* a globbing operation that fails causes the shell to print a diagnostic
and stop processing the current command or script, i.e.

csh> echo *.d
echo: No match.
csh>

Being able to toggle this behavior is, I believe, a desirable thing.
The first style of behavior should probably be the default, but
for those who want the shell to warn them of errors, the second
could be done by setting a variable, such as `nomatch'. Note
that 4.3 csh uses the `nonomatch' variable to cause the first style
of behavior to occur.
