It's the shell that expands wild cards, and it will attempt to fork and
exec rm(1) with an arg list of all matching files. rm(1) itself has no
concept of wildcards -- it expects a list of filenames.
As you have discovered, it is very easy to overload the argument list.
There are many ways around this, but one of the best ones is to use
xargs(1). eg:
% ls -1 | xargs rm
