def compute_segment_pattern
  normalized = filter_argument.delete_prefix("/")
  escaped = Regexp.escape(normalized)
  boundary = '(?:\A|/)'

  if normalized.end_with?("/")
    # Trailing slash signals directory-only matching.
    /#{boundary}#{escaped}/
  elsif normalized.include?(".") && !normalized.include?("/")
    # Bare filename pattern ("test.rb" matches "faked_test.rb"): allow a
    # substring match within a single path segment. Multi-segment arguments
    # must not get this relaxation, or "app/models/user.rb" would also
    # match "webapp/models/user.rb". No boundary here: `[^/]*` already
    # reaches back to the segment start, so prefixing one matches the same
    # paths.
    %r{[^/]*#{escaped}(?=[/.]|\z)}
  else
    # Require a segment-boundary match so "lib" matches "lib/" but not
    # "library/".
    %r{#{boundary}#{escaped}(?=[/.]|\z)}
  end
end

#matches?(source_file) ⇒ Boolean

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".

Parameters:
