Patch to correct the long option listed in units.1

units(1) does not accept the '--historyfile' long option as documented in the
man page, it accepts the long option '--history'.  The man page says these
options are "for compatibility with GNU units", and the GNU units documentation
agrees with the implemented option '--history'.


>From the man page
     -H filename , --historyfile filename
             Ignored, for compatibility with GNU units.

>From the source, in the 'longopts' array
        {"history", required_argument, NULL, 'H'},


How to reproduce:

$ units --historyfile filename </dev/null >/dev/null
units: unrecognized option `--historyfile'
usage: units [-f unitsfile] [-H historyfile] [-UVq] [from-unit to-unit]

$ units --history filename </dev/null >/dev/null
