I agree and was about to commit the patch. Then I greped
the code and found that we use this pattern quite frequently
(10s of places). There are also 6 local definitions for an
ARRAYLEN or ARRAY_LEN macro that nicely encapsulate
the sizeof() magic.
Given that people seem to like open arrays (spares the
invention of yet another constant), I suggest we introduce
SVN_ARRAY_LEN (or SVN__ARRAY_LEN) and use that
consistently.
