File externals included in svn status --quite

[Kevinm <ke...@gmail.com>]

When running svn status in an unmodified working copy, file externals are
included in the output regardless of whether the --quiet flag is supplied.
This seems wrong as my assumption is that running status with the --quiet
flag on a unmodified wc should return no output.

This breaks the current version of svnmerge.py as it assumes that a wc has
local modifications if running 'svn status --quiet --ignore-externals'
produces any output.

Running status with --ignore-externals also has no effect on file externals
but this seems correct as a file external is treated as a normal file when
committing (just with a different repository parent).

Are my assumptions correct? If so, I'll post to the developers list.

Thanks.
