Bug#833779: devscripts: [uscan] please strip whitespace in href when matching URLs

[Daniel Kahn Gillmor]

Package: devscripts
Version: 2.16.6
Severity: normal

sks is released here:

 https://bitbucket.org/skskeyserver/sks-keyserver/downloads

the HTML there is decidedly weird, with extra whitespace in the href:

---------
             <td class="name"><a class="execute" href="
                    /skskeyserver/sks-keyserver/downloads/sks-1.1.6.tgz">sks-1.1.6.tgz</a>
            </td>
---------

So uscan isn't able to find it.

I reported the issue to bitbucket:

https://bitbucket.org/site/master/issues/13130/downloads-page-has-spurious-whitespace

and got this response on IRC (#bitbucket on freenode):

11:29 <+dwfreed> dkg: browsers ignore the whitespace
11:30 <+dwfreed> URLs can't have spaces in them anyway, which is what the field is
11:30 <+dwfreed> it must be encoded, either as + or %20
11:30 <+dwfreed> so teach the tracker to adhere to the spec


i don't really care which party fixes this issue -- or if both parties
do -- i just want uscan to work again for sks without my working
around it by adding an extra whitespace matcher to sks:debian/watch.

thanks for maintaining this infrastructure,
