Sorry, of course, you're right. I wasn't paying attention. Change
"unlink" to something that will cause perl to call "svn rm" with the
argument $_ instead.

I'm sure it can be written in most any scripting language, or even a
compiled program. Whatever you have at your disposal.

I don't know a way to tell sed to use a null byte between output
lines instead of a newline.

However, the tr utility can translate newlines to null bytes.

svn st --depth=infinity \
| sed -n "s/^\! //p" \
| tr "\n" "\0" \
| xargs -0 -n 1 svn rm
