No functional change intended. This commit only changes formatting
to the style we recently use, e.g. starting the body of a test with a
single quote on the same line as the header, and then having the test
indented in the following lines.
Whenever we change directories, we do that in subshells.
All look sensible; I think it is OK to also do minor and trivial
tweaks here, but let's see what 2/6 does.
