[Pdx-pm] command line options

[Thomas J Keller]

Thanks Randal, Colin, and Bruce.
Weird, but (apparently) with \cM as a line-ending you have to specify 
both in ($/) w/ -015 and out ($\) w/ -l
  If not it either reads in as a single line, or outputs as a single 
line.
This worked:
perl -i.bak -015 -l -pe 's/\s+/\t/g' input.txt

Thanks again,
Tom K
