[ruby-list:31915] RDtool Include patch

るびきちです。

存在しないRDファイルをIncludeしようとした場合、
このように変な例外が発生しますが、

●:243:in `parse': undefined method `push' for "":String (NameError)
	from :487:in `parse_subtree'
	from ●:354:in `next_token'
	from :351:in `if_current_indent_equal'
	from ●:351:in `next_token'
	from /usr/local/lib/ruby/site_ruby/1.6/racc/parser.rb:97:in `_racc_do_parse_c'
	from /usr/local/lib/ruby/site_ruby/1.6/racc/parser.rb:97:in `__send__'
	from /usr/local/lib/ruby/site_ruby/1.6/racc/parser.rb:97:in `do_parse'
	from :262:in `parse'
	from /usr/local/lib/ruby/site_ruby/1.6/rd/tree.rb:44:in `parse'
	from /usr/local/bin/rd2:207

Warningを出して無視するようなにパッチを書きました。
