Because it's not a module flag, it's a parser flag (like --help). It's a
system wide setting and some modules already use a "-o" flag.

No, documenting it needs a general solution, not just raster modules.
See Markus's post.
Doing something like "add to all r.* html pages" should be automated,
not done by hand. Makes it 1000% easier to maintain that way.
Also, there is the GIS variable "OVERWRITE" (g.gisenv)
toggles map overwrite.
With 0 maps are protected (default),
With 1 maps with identical names will be overwritten.
You can force a protected overwrite by adding "--o" to the command.
So "--o" is documented somewhere, it is just a bit hidden.
