BTW, that is already reasonably DRY, in my opinion. Calling the same
method repeatedly but with different parameters is not "repeating
yourself". It would be WET (hrm...Way Extra Toomuchcode) if you had
something like:

d = d.gsub( /\r\n/, ' ' )
e = e.gsub( /\r\n/, ' ' )
f = f.gsub( /\r\n/, ' ' )
g = g.gsub( /\r\n/, ' ' )
etc.

It's just semantics, but IMO what you're asking for is to make your
code more compact (but not necessarily golfing).
