Redirect error from front page postcode form

[handelaar]

(Version: current master, UK configuration and data, brand new install.)

Something (and I am unable to tell exactly what, sorry) causes the front-and-centre postcode lookup form POSTed to mapit.views.postcodes.postcode to fail, and redirect incorrectly to a 404 for

http://mapithost.domain.tld/postcode/mapit.views.postcodes.postcode

Possibly a missing reverse() function on the urlconf?

(I hasten to add that I in no way actually need that page to work, but I figure it wants logging.)

The current URL, postcode/mapit.views.postcodes.postcode, didn't match any of these.

That code does work on mapit.mysociety.org:

§ curl -v -d pc=B24QA https://mapit.mysociety.org/postcode/
[…]
< Location: https://mapit.mysociety.org/postcode/B24QA.html

Ah, if you include a non-alphanumeric/space character, then the reverse of 'mapit.views.postcodes.postcode' fails, and so what you see happens:

§ curl -v -d pc=B24QA. https://mapit.mysociety.org/postcode/
[…]
< Location: https://mapit.mysociety.org/postcode/mapit.views.postcodes.postcode

We should strip those characters first, presumably.

3-line patch submitted for review

OK yes, just changing the one problematic line is a better (and also functional) solution. :)

Thanks for spotting!
