In this project, we write what area of the codebase the change
affects before the colon (I'll give you an example later).

Isn't it a bug in zsh that it does not understand that the comment
is about the command placed on the downstream of the pipe, like
this example?

	echo a b c |
	# upcase the input (a comment about the next line)
	tr a-z A-Z

Apparently bash is happy with the existing code, and dash and ksh
seems to be OK with the above construct, too.

Perhaps rephrase the log message like this instead?

    [PATCH] completion: work around zsh comment but in __git_complete_worktree_paths

    In contrib/completion/git-completion.bash, there is a construct
    where comment lines are placed between the command that is on
    the upstream of a pipe and the command that is on the downstream
    of a pipe in __git_complete_worktree_paths function.

    Unfortunately, this script is also used by Zsh completion, but
    Zsh mishandles this construct, resulting in a breakage:

        $ git worktree remove [TAB]
        $ git worktree remove __git_complete_worktree_paths:7: command not found: #

    Move the comment, even though it explains what happens on the
    downstream of the pipe and logically belongs where it is right
    now, before the entire pipeline, to work around this problem.

It might also be necessary to consider rephrasing the comment
itself, not just "Move the comment", to make sure that it is still
appropriate when used as a comment to cover the whole pipeline---the
original was meant to explain what happens in the downstream only.

Thanks.

[PATCH]: contrib/completion/git-completion.bash, there is a construct
where comment lines are placed between the command that is on
the upstream of a pipe and the command that is on the downstream
of a pipe in __git_complete_worktree_paths function.

Unfortunately, this script is also used by Zsh completion, but
Zsh mishandles this construct when "interactive_comments" option is not
set (by default it is off on macOS), resulting in a breakage:

$ git worktree remove [TAB]
$ git worktree remove __git_complete_worktree_paths:7: command not found: #

Move the comment, even though it explains what happens on the
downstream of the pipe and logically belongs where it is right
now, before the entire pipeline, to work around this problem.
