[DRE-maint] Bug#470642: libwww-mechanize-ruby1.8: uri scheme is case sensitive

[Saku Ytti]

Package: libwww-mechanize-ruby1.8
Version: 0.7.2-1
Severity: normal

I'm opening
'http://www.cisco.com/cgi-bin/Support/Bugtool/bugnav2.pl?swver1=&fset1=&severity1=&resultsperpage1=&target1=&train1=&swver=%3F&target=%3F&train=%3F&mdf_label=Cisco+IOS+Releases&rneflag=0&swver2=%3F&target2=%3F&train2=%3F&fset=%3F&operator=and&resultsperpage=500&severity=%3C%3D+6&statusO=O&statusF=F&statusUC=UC&statusJ=J&statusD=D&Submit=+++Next+++&cco_product=IOS'
which redirects to web form based authentication, when I authenticate,
mechanize raises exception:

/usr/lib/ruby/1.8/www/mechanize.rb:432:in `fetch_request': unsupported scheme (RuntimeError)

This is because the scheme actually was HTTP. I made following change to
mechanize.rb which actually fixes the problem and provides better debug.

432c432
<       raise "unsupported scheme: #{uri.scheme}" unless ['http', 'https'].include?(uri.scheme.downcase)
---
>       raise "unsupported scheme" unless ['http', 'https'].include?(uri.scheme)
442c442
<       raise "unsupported scheme: #{uri.scheme}" unless ['http', 'https'].include?(uri.scheme.downcase)

>       raise "unsupported scheme" unless ['http', 'https'].include?(uri.scheme)
