I think I have worked out what is wrong.

Before my change, the test suite's "--http-library" option defaulted to
"neon". Back in the 1.6 days and earlier, that was sensible.

Because Serf is now the default, I changed the test suite's
"--http-library" option to default to "serf", and also made the test
suite always tell Subversion (via a config option) to prefer to use
whichever library the test suite was told to use. I thought that made

What's happening here, I think, is the macosx/neon build-bot is building
Subversion with Neon only, and passing no "--http-library" option to the
test suite. I've changed the default assumption so it now gets it wrong.

So my change to the default value was poor. Instead I should restore the
default of "neon" and document what the option really means. (It means:
make svn use this library if it supports both; otherwise just assume it
is using this library.)
