Subject: Re: Automatic globbing of ARGV

Just to clear things out, I am using win32.

So I created a test.c program:
  void main(int argc, char *argv[])
  {
    int i;
    for (i = 0; i < argc; i++)
      printf("%s\n", argv[i]);
  }

test.exe *.c
=> *.c

Which indicates that ruby does the globbing.

Finally, after looking into the ruby source, I can see that in fact,
ruby calls "ruby_globi" in win32.c. This also explains why dir-glob,
'**', worked.
