Tags with + do not show when seraching for one user

[g0ren]

When searching for a tag containing the + sign for a particular user through the default web interface, it doesn't show any results even when there are known to be results to be shown. For global search for the same tag, however, it works okay. For one instance, compare http://bnw.im/u/goren/t/h%2B vs. http://bnw.im/t/h%2B

I did, right in the header. That's how you do it on github.
Now just wait for 2017 to come, when @stiletto will merge that PR and deploy fixed version.
