The problem is that this is the default zsh prompt.  Even if I fix it
for myself, it may still break for everyone else in the future.  Do
you want to put a fix in CVS, adjust the FAQ, or just leave things as
they are?

It actually looks to me like the Tramp shell pattern by default does
match two % signs.  After experimenting, the shell pattern doesn't
match the actual prompt in the Tramp interaction, but matches the
string I see in the log:

(string-match tramp-shell-prompt-pattern 
"^[[1m^[[7m%^[[m^[[1m^[[mprod-perf-db01%")
-> 0

so I'm not sure where the problem is.  Note that ^[ above is actually
C-q ESC.  I can't tell you why zsh is sending ANSI escapes to a dumb
terminal.

My fix, which you could put in the FAQ, is to just do:

[ $TERM = "dumb" ] && setopt NO_zle && PS1=""

which works.
