No, people don't want to be able to see proc mounts by default.  But
for proc mounts, fsu.fsu_blocks should be zero so the following code
in show_dev should prevent the mount from being listed:

  if (fsu.fsu_blocks == 0 && !show_all_fs && !show_listed_fs)
    return;

Can you please investigate why that isn't happening for you?
I'm worried that your fix masks out a more-fundamental bug.
Thanks.
