I can reproduce this.  For me the backslashed lines show the local-apt-
repository information from `apt-cache policy`'s output.  It's caused
by the `apt install hello/sid` completion logic (I can reproduce it with
'apt install hello/<TAB>').  This fixes it:

diff --git a/Completion/Debian/Command/_apt b/Completion/Debian/Command/_apt

... although I wouldn't object to changing the patterns to «*[ ,]a=».
