[PATCH] more 1.9 warning fixes

[Eric Hodel]

May I apply these patches?

@sspi_enable is not initialized in lib/net/http.rb

pos is shadowed in IRB::OutputFormat#foo, but I don't see where foo is
called at all, so I removed the method. If #foo is actually used,
removing 'pos = 0' would be sufficient.
