Hey Stefan,
This is the old patch I sent before, but there is also lots of useful

We usually just name pointer arguments by their name without the
star, so just @a path is OK.
Pointers to pointers are sometimes referred to as @a *path, depending
on what the docstring is trying to say.

I think 'strictly' is not what we want here, right?
The code uses svn_wc_is_wc_root() which is not "strict", and
that's fine.

This still throws an error on compilation:
subversion/libsvn_wc/update_editor.c:5357: error: ‘pool’ undeclared
(first use in this function)
subversion/libsvn_wc/update_editor.c:5357: error: (Each undeclared
identifier is reported only once
subversion/libsvn_wc/update_editor.c:5357: error: for each function it
appears in.)

It's not necessary to repeat details from the docstring in the
log message. But it does not hurt, either.

Rest looks good.
