These are both mostly trivial changes.
The first one makes it so that the script works on systems where Bash is not symlinked to /bin/sh like Alpine Linux and FreeBSD. I'm not 100% sure what that line is trying to do. I read the commit (a41c632) that added it and I couldn't make sense of it. Either way,
BASH_SOURCE == BASH_SOURCE[0]
which is equal to$0
when the script isn't getting sourced. The script is meant to be run, not sourced, so the change should be fine.The second change just quotes the path in case someone's
XDG_CACHE_HOME
has a space in it. And it's good for consistency.
