  if normalized.include?(".")
    # Filename pattern (e.g. "test.rb" matches "faked_test.rb"): allow
    # substring match within the last path segment, anchored to a
    # segment boundary.

    # Trailing slash signals directory-only matching.
    /#{boundary}#{escaped}/

    # Directory or path: require a segment-boundary match so "lib"
    # matches "lib/" but not "library/".

    #matches?(source_file)  ⇒ Boolean 
  



  

    
Returns true when the given source file's filename matches the
string configured when initializing this Filter with StringFilter.new('somestring').
Matching is path-segment-aware: the argument must appear immediately after a "/"
and be followed by "/" or end-of-string, so "lib" matches "/lib/foo.rb" but not
"/app/models/library.rb".
