I've started working on this. 'mtn automate update' is implemented;
see cmd_merging.cc in 2cc8eafc9f3350379e72c47c24e567ffc52d7fbc in
branch nvm.stephe. There's a test for it. It was easy, since there is
no output to format (it's progress, not useful for parsing).

I added a new Lua function 'change_workspace' (cmd_automate.cc in
f0b5f85a97853d52f94fd3aab2606ba093a40bff), which basically calls
paths.cc go_to_workspace.

My Lua function now looks like this (the rest is unchanged from the
previous post):

function gds_update_all()
   local workspaces = gds_find_workspaces (gds_missions)
   local status, output

   if 0 == # workspaces then
      error("no GDS workspaces found")
   end

   for _, ws in pairs(workspaces) do
       change_workspace(ws)
       io.stderr:write(ws)
       status, output = mtn_automate("update")

       -- output is stdout; stderr is output already.
       if status ~= 0 then
          io.stderr:write(" failed\n")
       else
          io.stderr:write("n")
       end
   end
end

This basically works, but I'm getting errors about writing the options file:

mtn: warning: Failed to write options file _MTN/options: error: renaming 
'_MTN/mtdkyfvx.tmp' to '_MTN/options' failed: Access is denied. (5)

This is comming from the workspace constructor in update.

The actual update succeeds, but the temp options file is left.

It appears that something has the options file locked, but I can't
figure out what. Any hints?

Any comments on 'automate update' or 'change_workspace'?
