Copyright detection sees URLs containing copyright symbols as copyright statements

[petergardfjall]

Description

Scancode sometimes produces copyrights where none are actually to be found.
In this case it appears to be thrown off by URLs containing a copyright character.
(I'll file this as a bug although it might be a feature/improvement.)

One case is this test file of 10000 URLs (see urls.10K) where Scancode v32.5.0 manages to find a "copyright statement" like:

{
  "copyright": "(c) /axove+xose/7,-1,0,B/frameset&F axuntanza&1,,3 http://biblio.cesga.es:81/search",
  "start_line": 4569,
  "end_line": 4570
}

and

{
  "copyright": "(c) /axove+xose/7,-1,0,B/frameset&F axuntanza&3,,3 http://db.zaq.ne.jp/asp/bbs/jttk_baasc506_1/article/36 http://db.zaq.ne.jp/asp/bbs/jttk_baasc506_1/article/37
