I guess, something went wrong with this one, bug I wasn't able to locate the
problem, yet.
Before this checkin, I (as expected) go some output with `mclient -lx`,
e.g.:
$ mclient -lx
Welcome to mclient, the MonetDB/XQuery interactive terminal
Type \q to quit, \? for a list of available commands
xquery>1+2
more><>
3
xquery>
After this checkin, I don't get any output at all any more,
e.g.:
$ mclient -lx
Welcome to mclient, the MonetDB/XQuery interactive terminal
Type \q to quit, \? for a list of available commands
xquery>1+2
more><>

Likewise, before `Mtest.py -r` resulted in
23 out of 1861 tests produced SIGNIFICANTLY different output
now it results in
1010 out of 1863 tests produced SIGNIFICANTLY different output
mainly as most tests don't produce any output at all (as indicated above).
