Would be great to get an error messages and backup failure if an exclude statement has invalid syntax

[framps]

I added a dummy line with some random contents and didn't get an error message and no backup failure.

# Raspberry Pi Image Cleanup Exclude File

# Usage
# RF    = remove file
# RD    = remove directory
# RT    = remove tree (removes directory and everything in it)
# RFID  = remove all files in directory
# RAIT  = remove all in tree (removes all in the directory and subdirectories but keeps the tree)
# RAID  = remove all in directory (removes everything in the directory)
# <C2><A7>USER = is replaced with the actual user

rdlprmf

# Allgemeine tempor<C3><A4>re/ver<C3><A4>nderliche Daten
rait = /var/cache/apt/archives
rait = /var/tmp
rait = /tmp
rait = /proc

I also noticed

# Optional: Nur Englisch/Deutsch behalten
#find /usr/share/locale -mindepth 1 -maxdepth 1 ! -name "de" ! -name "en" -exec rm -rf {} +

I didn't test to add invalid commands or commands with syntax errors. Hope any errors will terminate the backup.
