Rsync is failing with confusing error messages

In a bash script (Arch Linux) I have the following rsync command:

rsync –nvaAHX --inplace --delete-delay --exclude-from="/etc/$path1/exclude-list-$configName.txt" "$new_snap/" "$BACKUPDIR"

The rsync command fails with the following error:

rsync: --delete does not work without --recursive (-r) or --dirs (-d).

Of course, that message is misleading as "a" implies "r".

If I remove the option "–delete-delay" from the rsync command, I get this different error:

rsync: link_stat "/some/path/–aAHX" failed: No such file or directory (2)

The value shown at "/some/path" is the current working directory. If I change the current directory, that value in the error message changes as well. However, why the options "-aAHX" would be appended to any part of the path is confusing.

The computer is a fully updated Arch Linux system. I just rebooted it as well.

4.13.11-1-ARCH #1 SMP PREEMPT Thu Nov 2 10:25:56 CET 2017 x86_64 GNU/Linux

rsync program location:

# which rsync
/usr/bin/rsync

Here is the test script:

#!/bin/bash

path1=xyz
configName=root
new_snap=/.snapshots/1/snapshot
BACKUPDIR=/backup/$configName

echo "showing exclude file contents:"

cat "/etc/$path1/exclude-list-$configName.txt"

echo

echo rsync –nvaAHX --inplace --delete-delay --exclude-from="/etc/$path1/exclude-list-$configName.txt" "$new_snap/" "$BACKUPDIR"

rsync –nvaAHX --inplace --delete-delay --exclude-from="/etc/$path1/exclude-list-$configName.txt" "$new_snap/" "$BACKUPDIR"

Here are the contents of the file "/etc/$path/exclude-list-$configName.txt":

"dev/*"
"proc/*"
"sys/*"
"tmp/*"
"run/*"
"mnt/*"
"media/*"
"lost+found"
".trash*/*"
".Trash*/*"

Here is some testing without any script at all. I find it baffling.
