Earlier I got a nice release string when invoking mkgmap.jar with the argument --version.

With the latest trunk release r7850  downloadable I get 'unknown':
PS P:\> java -jar tools/mkgmap/mkgmap.jar --version
Time started: Thu Oct 24 09:02:44 CEST 2013
unknown
Got that also on selfcompiled versions earlier and with intermediate downloads (just the mkgmap.jar) but there I thought rXXXX is only contained if properly compiled on the servers...

is that on purpose ?
.... the option '--version' is still mentioned in the --help=options output.

Thanks and regards
