I could be missing something, but:
[[ $'\nwombat' =~ $'wombat' ]] && \
echo "These compare as equal, with or without the leading \n"
They do not compare as equal with the == operator or the = operator. You
probably want the = operator, because the == operator _does_ interpret
the RHS as a glob. The = operator just uses simple string comparison,
without interpreting anything.
I am curious about why the space was included at the end of the in the
expression:

Does get_mounts add a space to the end of its output?
