Setting PREFIX and SUFFIX this way changes things (apparently for the
better, the code works very well with them, except for $(<TAB> as I
shown in other video, the "Better" one), but it's interesting that
PREFIX and SUFFIX do not change their values, I showed this in
following video:

https://asciinema.org/a/cf8yrmdzjqy7r2kz42091ujts

If I do PREFIX="$PREFIX" SUFFIX="$SUFFIX" then it doesn't change
things, interestingly, it's like no assignment would be done.

Best regards,
Sebastian
