I had a closer look at the data. The cases I saw were:
  * An extra space after the IRI.
  * An extra space before the IRI.
  * Legitimate-looking spaces in file or directory names in PATH.
  * Unescaped multi-word human-readable strings as query parameter  
  * Space in query parameter name.

  * IRI included twice accidentally with " <" in between. (One case.)
  * Text meant to be alt text as href. (One case.)

I didn't notice a single case that looked like the consequence of a  
missing quote.
