doc: correct doc for glob pathspec

gitglossary documents Git pathspecs. One type of pathspec is the "glob"
pathspec, prefixed with the magic word "glob".

Regarding glob pathspecs, gitglossary says, '"**/foo" matches file or
directory "foo" anywhere, the same as pattern "foo".' That last phrase
('the same as pattern "foo") is incorrect. "**/foo" and "foo" are not
equivalent. "**/foo" matches foo anywhere, but "foo" does not.

This change removes the incorrect phrase from the glob pathspec doc.
