In :s[ubstitute], \n in the pattern finds a newline, \r in the
replace-by string breaks the line.

In substitute(), \n both finds a newline or replaces by one, but if the
string is got from or inserted into a file, a newline in the string may
mean a null byte in the file, depending how you lift the string or put
it back. (IIUC, a newline in a register still means a linebreak in the
file, but there, there is another hitch: any register whose contents end
in a newline is regarded as linewise.)
