It's the way Unix works.  Individual commands typically know nothing of
'*' or '[abc]'.  The shell "globs" the command, expanding it to all the
matching files, and then hands that list to the command as individual
arguments.

However, sometimes that expansion exceeds the maximum argument size, as
you discovered.

If you have perl, try this:

  perl -e 'unlink glob("*")'

It uses Perl's internal glob() function, which can handle an unlimited
number of files.
