Omnibox: Don't Promote Intranet Hostnames Pound Sign Space Whatever ("c# foo")

Omnibox: Don't Promote Intranet Hostnames Pound Sign Space Whatever ("c# foo")

Suppose you have an intranet hostname "c" that you've previously visited.

After this change, the behavior will be as follows:
input  ->  inline suggestion (what happens what you hit return)
c -> navigate to URL
c/ -> navigate to URL
c#foo -> search (this behavior differs from before this change)
c# foo -> search (this behavior differs from before this change)
c#  foo -> search (this behavior differs from before this change)
c# -> search (this behavior differs from before this change)
c#  -> search (this behavior differs from before this change) (notice the extra spaces the URL parser drops them)
c/#foo -> navigate to URL
