This is fixed in latest RubyGems. If the LoadError file does not
match the original feature, the exception is re-raised immediately.

require will always try 'foo.rb' or similar, bin path files are
loaded with #load, instead. It is a cheap trick.
$ echo 'puts "foo"' > foo
$ echo 'puts "foo.rb"' > foo.rb
$ ruby -rfoo -e0
$ ruby -e 'load "foo"'
