You're probably using "bash-completion", which is a separate project
from bash, and is known to have many flaws.

And in regular bash (without bash-completion), I see this:

wooledg:/tmp/x$ rm 'this
is
one
file' _

where _ is the cursor.

In bash, $'...' is a special form of quoting which acts like
single-quoting except that certain backslash+letter sequences are expanded
in a way that's similar to C's strings.  For example, \n expands to a
newline character, and \t to a tab.  See the man page for full details.

wooledg:~$ printf %s $' \t\n' | od -tx1 -An
 20 09 0a

It's the cleanest way to specify special characters in an argument string
or a variable assignment.
