I tried this patch vs. CVS HEAD used my usual configure option with
only --with-prefix set, then tried to make, and got:
make[3]: *** No rule to make target `parse_cte.o', needed by `objfiles.txt'. Stop.
make[3]: Leaving directory `/home/shackle/pgsql/src/backend/parser'
make[2]: *** [parser-recursive] Error 2
make[2]: Leaving directory `/home/shackle/pgsql/src/backend'
make[1]: *** [all] Error 2
make[1]: Leaving directory `/home/shackle/pgsql/src'
make: *** [all] Error 2
Is there something missing?

I apologize for that. I rearranged it last night because the name was
not scalable, but delayed sending this out until today. It can now be
found at
<http://git.postgresql.org/?p=~davidfetter/with_recursive/.git;a=summary>
To pull from the new location, in your .git/config, change URL from something
like the following:
url = git://davidfetter@git.postgresql.org/git/~davidfetter/postgresql/.git
to
url = git://davidfetter@git.postgresql.org/git/~davidfetter/with_recursive/.git

This can be done at query time already using arrays per Asaba-san's
suggestion. I'll add some examples to the documentation.

Wonderful!
