Control: retitle -1 zsh: Modifying HELPDIR comes too late, doesn't catch .zwc files
Control: tag -1 + confirmed

Sorry, but that's clearly not true: Since zsh_5.8.orig.tar.xz does not
contain any .zwc file, all .zwc files in the binary packages can't be
anything else than compiled from the bundled source at package build
time.

Can confirm that, though.

Hrm, yes, but this is caused by this sed call in debian/rules:

  # Doesn't this need to go before we zcompile stuff into .zwc files? -- Axel
  	sed -i -e 's,^local HELPDIR=.*,local HELPDIR=$${HELPDIR:-/usr/share/zsh/help},; s,:-more,:-/usr/bin/pager,;' \
  		debian/zsh-common/usr/share/zsh/functions/Misc/run-help
  	sed -i -e '1!b;s:^#!.*[ /]zsh:#!/bin/zsh:;s#/usr/local/bin#/usr/bin#;' \
  		`find debian/zsh-common/usr/share/zsh/functions -type f`

Actually your issue is already mentioned in form of the question in
the comment in front of that rule. Or in other words: Your bug report
just answered that question with "yes". :-)

Retitling the bug report accordingly.
