Having an application-specific env variable also makes this kind of
workaround more palatable -- setting SVN_EDITOR strangely shouldn't
break anything else, and if it does, it's the fault of the something

I checked; turns out that /usr/bin/emacs is a script that invokes
basename (in the standard Centos 5.5 emacs install). I copied
/usr/bin/emacs to /home/path with spaces/bin/emacs for this test.
It looks like the workaround of quoting the path with spaces in
SVN_EDITOR works, and I'm now encountering a bug in emacs (or perhaps
the Centos packaging of Emacs). (The emacs script is easily fixed to
tolerate spaces in its path, just by doing the basic obvious things
you do when shell scripting.)

Yes, that would be simpler. But as I said in my initial post, I first
discovered this on Windows under Cygwin. Avoiding "c:/Program Files"
and "c:/Documents and Settings/david.dyer-bennet/My Documents"
involves contortions and leaves you putting things in unusual places.
Linux defines spaces as valid characters in paths and filenames, so
people are going to try to use them. And Subversion does support
(Spelling nit, no flame intended: "moral"; not "morale". They're
both real words with quite different meanings, so it's of value to
keep them distinct. And now I have no doubt guaranteed 3 basic
language mistakes of my own somewhere in this message :-) .)
