Line continuation bug in tables?

I have the raw adoc content:

[width="100%",cols="1,1,2,3",options="header",]

Note the `\` line continuations. The output looks as follows:



The line wrapping seems to work (with '+', I get hard breaks), but the `\` are retained. I think this must be an error?

Of course, 1 minute after posting, it occurred to me that it might work as I wanted with no line continuation character at all, and it does. So that means that the `\` is only sometimes parsed as a line continuation control character?
