This lib-git-svn.sh patch (above) has a quite serious fault :(

I'm very annoyed with myself, because I was trying so hard to be
conservative and safe! :-P

The original branch containing these lib-git-svn.sh patches (#3-5 in the
original series) had another commit with the highly informative commit
message: WIP. I could not remember what this commit was about, or if it
was complete (but I thought not), so I didn't send it along with the
others ... Well, this evening I remembered what it was about, along
with the fact that it fixed a problem with the above and that I had
intended to squash all of these patches into one.

The problem with the above is this: because lib-git-svn.sh is sourced
by 57 test files, only four of which even remotely care about using
apache, if SVN_HTTPD_PORT is set and your apache install cannot be
found, then *all* 57 tests will be skipped.

Sorry about that ...

I've added a diff of the additional commit below (well, I changed a
couple of "test ! -e" to "test ! -f", given your comment on patch
04/14) so you can see that the fix will involve moving the code used
to check your apache installation into a separate function which will
only be called from start_httpd; ie only tests that want to use the
web-server will execute this code.

I'll send a proper patch soon. Again, I must apologize for messing up!

ATB,
Ramsay Jones
