Log::Log4perl::Resurrector deletes blank lines before a ###l4p comment

[fellowsr]

The current regex in Log::Log4perl::Resurrector to match the special ###l4p comments will remove blank lines before the comment as \s* will match newlines as well as whitespace.

This causes line numbers in logs to not match the line in the original source file.

Limited testing suggests replacing the pattern with:-

  # Orig
  #$text =~ s/^\s*###l4p//mg;
  # Patch
  $text =~ s/^[ \t]*###l4p//mg;

fixes this issue.
