The pattern that this functions searches for determines the tag
uniquely. But here's a catch: no programming language creates distinc
entities (ones that end up in the tag), based only on trailing space.
I.e. "foo()" and " foo() " always refer to the same thing.
So this change gives 2 improvements:
1. Emacs gonna stop failing finding a tag when someone simply
reindented the sources
2. As a side effect, this works around a problem, when a
tags-generating program trimmed the whitespace (the commit has a link
to anjuta-tags bugreport about that).

"CR" is part of the whitespace, so per description above comparison to
it is simply unnecessary.
