While this works I think it would be better to be a bit more precise,
eg. /^#*\s*(?:\S+\s+){5}\s+root/ (match non-whitespace followed by
whitespace 5 times).

Alternatively, the initial regex could be turned to non-greedy by just
appending a '?' to the '+': /^#*(.+?) root/, that way it shouldn't match
past the first 'root'.
