leading spaces and Perl.

Hi Lance,

When you say that

  s/^\s//;

doesn't work (presumably to remove leading spaces), what do you mean? Are
you sure you are operating on the right variable? For example, don't do

  foreach my $line ( @lines ) {
    s/^\s//;
  }

because $line will remain untouched.
