I had a longer look at this and can't find any issues with the code or
documentation changes.
I did wonder whether it would be worth mentioning that any initdb
options set in "PG_TEST_INITDB_EXTRA_OPTS" will override those
which can be set by pg_regress, but of the four ("--no-clean", "--no-sync",
"--debug" and "--no-locale"), only the optional "--no-locale" can actually
be overridden, so it doesn't seem important.
