Bug #6025: IRB test: failure caused by non-guarded completion test

Hello,

While testing for 1.9.3-p105 release, found the following test fail:

<pre>
 65) Failure:
test_nonstring_module_name(TestIRB::TestCompletion) [C:/Users/Luis/Projects/oss/ruby/test/irb/test_completion.rb:13]:
[ruby-core:42244].
<[]> expected but was
<["C:/Users/Luis/Projects/oss/ruby/lib/rubygems/custom_require.rb:36:in `require': cannot load such
file -- readline (LoadError)",
 "\tfrom C:/Users/Luis/Projects/oss/ruby/lib/rubygems/custom_require.rb:36:in `require'",
 "\tfrom C:/Users/Luis/Projects/oss/ruby/lib/irb/completion.rb:9:in `<top (required)>'",
 "\tfrom C:/Users/Luis/Projects/oss/ruby/lib/rubygems/custom_require.rb:36:in `require'",
 "\tfrom C:/Users/Luis/Projects/oss/ruby/lib/rubygems/custom_require.rb:36:in `require'"]>.
</pre>

RubyInstaller builds do not include GNU Readline and instead uses rb-readline replacement.

It fails to load it's replacement and because of that, fails to load and complete the test.

A guard against it perhaps needs to be implemented.

Ruby 1.9.3-p0 did not present this failure.

Thank you
