Similarly, I get:
Command not found:
   ["less "]

It would seem that in my case I have export PAGER='less '

I just changed that to deleted the space.

It seems quite reasonable to me to allow arguments using words or do
white space stripping.  Does this have the potential to cause
problems?  I guess the most obvious downside is that it gives some
expectation to users that we'll handle commands appropriately across
platforms.  What do others think?
