The % signs are necessary because after `}' in horizontal
mode TeX is in mid-line mode where it converts the
end-of-line character to a token for character 32 (` ') of
category 10 (space).  After that it enters state S (skipping
blanks) and ignores any further end-of-lines. (See The
TeXbook, p. 47.)
