\$\begingroup\$ I just love this approach, but you can use . instead of [^] since you only need to skip non-newline characters to find a newline, which saves 2 bytes. \$\endgroup\$

\$\begingroup\$ I don't think the ^ is necessary in the final regex, because any \n is already at the beginning of the string anyway, so that saves another byte. \$\endgroup\$

\$\begingroup\$ I've come up a way to golf the '$&'+' '.repeat(n). Basically that expression is just $& but with a space added each call, which is trivial to implement recursively - replace n=0 with r='$&' and f(z,n+1) with f(z,r+' ') and then r is the desired replacement string. If I've counted correctly that saves 12 bytes. \$\endgroup\$
