Thanks.  Probably this should be squashed with patch #1?

Test number's already taken.  9012 is free, though.

Is it impossible to test without svn present or otherwise speed
these up?  Some random ideas:

 - feed svn-fi output into svn-fe and compare git repos
 - check if "svn-fi after svn-fe" is idempotent (should it be?)
 - check for individual salient features from svn-fi output, using
   "grep", "sed", or "awk" to ignore the rest
 - use svnrdump in place of "svnadmin load" if available (is it
   faster?)
 - find the bottleneck in svnadmin and fix it

Of course at least one test of the "svn-fe | svnadmin load"
pipeline seems worthwhile; I'm just thinking we should avoid
habits that slow down the test suite too much.

Needed?  The svn_cmd function exists to point to a configuration
directory.

Where do the dates come from?  Why should I (the reader) expect
them?

Ah, you saw. :)

One possibility is to fuzz away whatever is unimportant when
comparing results (and using tools like "awk" to extract the
date to perform whatever tests on it are appropriate where it
matters).

What's wrong with this stream?

Maybe worth checking for the absence of svn:executable +
svn:special from an ordinary file, too?

Nice.  "replace symlink with executable" and "replace symlink
with directory" might also be interesting.
