885	Ignore space or %20 in webapi URLs	davidsarah	davidsarah	"When a wrapped URL is copied to the clipboard and then to a browser address bar, [http://allmydata.org/pipermail/tahoe-dev/2010-January/003508.html sometimes the copying application inserts spaces] at the end of each line and the browser does not strip them. This would happen in some cases even if URLs were shorter (#882), since they can include a filename and parameters.

I think it is only spaces that get inserted, not tabs. The browser might convert these to %20 when it submits the URL, so stripping spaces should be done after %-decoding.

Note that this isn't a duplicate of #884 ('give nice error page when URL is mangled') because we need to both:
 * strip spaces, in order to eliminate one of the most common forms of mangling, and
 * display a nice error page for mangled URLs that we're unable to correct."	defect	assigned	major	soon	code-frontend-web	1.5.0		usability newurls
