For now I recommend
   load '.../share/colors_mono.gp'

There was some discussion of building this in somehow
rather than requiring a separate "load" command.
One option is to add a "mono" option to the new
"set colors" command.

The drawback there is possible confusion that the existing
options (default | podo | classic) affect _only_ color, whereas
"mono" would affect color and linewidth and dash pattern.

Also related:

There is a proposal to add a command that would set
a repeat cycle for dashtypes, so that patterns 1-N would
be repeated for linetypes N+1 - 2N and so on.

We currently have such a command for linetypes 
"set linetype cycle"
but not for point types or dash patterns.

That is a known [unintended] problem. 
It's not obvious to me how to fix it, but I hope something will
be possible for -rc2.

Yes.
