[GRASS5] C string question

[Hamish]

v.labels will produce a string like "upper,left" for the ref= option.

the label file needs a space not a comma, thus we need to do a 
`tr ',' ' '` style cleansing of that.

How is this done? strchr()? code-snippet example?


thanks,
Hamish

ps - v.label, ps.map, and d.paint.labels all now support setting a
standard fontsize as well as the old size based on map units. Everything
should be backwards compatible.
