FYI: protect names starting with `-' in install-sh.

[Alexandre Duret-Lutz]

I'm installing this.  This protection was in mkinstalldirs, so
better put it in install-sh if we want to use `install-sh -d' 
instead of `mkinstalldirs' as discussed some months ago.

        * lib/install-sh (src, dst): Protect names starting with `-',
        as in mkinstalldirs.
