Compared to the previous version, it contains a new patch
[PATCH 1/3] cli/show: convert keyword options to booleans
This cleans up the argument parsing for show so that all heck doesn't break
lose when
we get more liberal with parsing keyword args.
This actually makes --exclude a new (undocumented) synonym --exclude=true;
arguably
this should be documented, but it's actually a global problem with the
documentation of
boolean arguments
