Ugh, apparently I've managed to miss the mentions of `add' and
`import'. But there are still issues I have with that description,
which might be why I missed it:

1. Ignoring `global-ignores', I don't see how svn:ignore can affect
   `add' and `import' -- first, `svn add foo.bar' will always work
   even if there is a "*.bar" pattern in `svn:ignore', so for adding
   files it makes no difference. Second, since the property applies
   only for the directory it is on, then adding a whole directory will
   work the same too (the directory is added no matter what its name
   is, and sub-files are added since the directory is no so it has no
   properties yet).

2. Same for `import'.

3. I'd expect that any such behavior would be documented in their
   reference sections. (Which is where I searched after your previous
   message...)

Well, I certainly didn't expect things to vanish... What I didn't get
from just the documentation is the fact that (with a "*.bar" pattern)
something like "svn add foo.bar" will work. After trying it out I
know that it does work, but I now don't know how would the ignore
property ever affect `add'/`import'.
