Personally, I find the lack of comments in many Mercurial test scripts
makes it quite hard to follow what's going on.  So when I work on test
scripts, I liberally add comments and/or guiding "echo" statements to
make it easier for me to understand what I'm working on.  So far no
one has complained.  ;-)
