Bug#799836: ps2pdf manpages say -dCompatibility not -dCompatibilityLevel

["Trent W. Buck" <trentbuck@gmail.com>]

Package: ghostscript
Version: 9.16~dfsg-2
Severity: minor
Tags: upstream patch

This fifteen-year-old bugfix appears to be incomplete:

    $ dgit clone ghostscript
    $ cd ghostscript
    $ git grep -B2 Compatibility=
    doc/History6.htm-2000/05/20 20:53:04 lpd)
    doc/History6.htm-       - The -dCompatibilityLevel= switch was incorrectly identified in one
    doc/History6.htm:place as -dCompatibility=. (doc/Ps2pdf.htm [1.11]: 2000/05/22 21:29:45 lpd)

Because it still appears in the manpages:

    man/de/ps2pdf.1:.B \-dCompatibility=1.x
    man/ps2pdf.1:.B \-dCompatibility=1.x
    man/ps2pdf.1:-dCompatibility=1.3 - - |

Please correct this from -dCompatibility= to -dCompatibilityLevel=.

The old variable has no effect:

    $ printf '%%!PS\n/Courier\n20 selectfont\n123 456 moveto\n(fnord) show\nshowpage\n' >example.ps
    $ ps2pdf12 -dCompatibility=1.7 example.ps - | pdfinfo - | grep version
    PDF version:    1.2
    $ ps2pdf12 -dCompatibilityLevel=1.7 example.ps - | pdfinfo - | grep version
    PDF version:    1.7
