} When I comment out the max-errors zstyle, zsh no longer hangs.

You're computing max-errors based on the length of the entire path, but
the effect of correction is applied to each individual component, so
you're allowing 18 corrections per filename in man1/ with the above.

Try changing to something like

zstyle -e ':completion:*:approximate:*' \
	max-errors 'reply=( $(( ($#PREFIX:t+$#SUFFIX:h)/3 )) )'

although that (and your original) allows no corrections unless there
are at least 6 characters already in the current word, so you might
want to use e.g. ($#PREFIX:t+2) or ($#PREFIX:t < 3 ? 3 : $#PREFIX:t).
