    Further tweak shell script portability in the hdtbl fonts examples.
    
    As gbranden@ rightly observed, the number of characters in the
    character class :cntrl: is locale-dependent, POSIX says that the
    repeat count in the second argument to tr can be omitted, and the
    transliteration target will grow to fit the size of the source.
    This actually works on OpenBSD, Debian Jessie, Solaris 11, and
    Solaris 9, so it seems quite portable indeed.
    
    People keep discussing all kinds of fancy changes on the mailing
    list, but fail to address the question of which is the minimal
    change required to get portable behaviour during the last minute
    before release.  Thus, i'm just making a decision and using the
    minimal tweak suggested by address@hidden
