Sorry, my mail to the zsh mailing-list got greylisted and I didn't
know whether it would have appeared in the archives before I had to
leave.

Here's a summary, for the record:

One can also reproduce the bug simply with:

    : | { : | tput init }
    : | { : | more }
    : | { : | less }

(the third one, with "less", is the most reliable to test workarounds,
as not all issues are visible with the first two).

A workaround is to use ( ) instead of { }, e.g.

    : | ( : | less )
