Notice the one/two spaces case:
 ~ # multipath -l

Currently only the space(s) between disk and major:minor are varying; but let's
make the space(s) between SCSI address and disk also variable, just in case.

 ~ # multipath -l | grep -o '\([#0-9]\+:\)\{3\}[#0-9]\+ \+[hs]d[a-z]\+ \+[0-9]\+:[0-9]\+'
 <<same output>>
