[GRASS5] [bug #885] (grass) d.histogram and -z flag

this bug's URL: http://intevation.de/rt/webrt?serial_num=885
-------------------------------------------------------------------------

Subject: d.histogram and -z flag

Platform: Linux/Intel
Linux distro: RedHat
linux cpu: Intel (i486, i586, pentium ...)
Xwindows version: Xfree 3.3.6
TclTk version: tcl/tk 8.3
grass downloaded at: CVS Server, Germany
grass binary for platform: I compiled the sources myself
grass sources source: yes, I am using the latest GRASS from CVS
c compiler name: gcc

The html man pages and the tcltkgrass module list the flag -z, but this flag is no longer supported by d.histogram.

I am not familiar with the code, so please could someone look into this?
