ARGH!

I've not yet been able to determine exactly where the problem is, though
the error certainly appears at the point where { 3_yd 38.42_cm } is
returned.  (That should be 38.1_cm, not 38.42_cm.)  I cannot figure out why
an extra .32_cm was added.  Unfortunately I do not have my copy of the src
available just now to look at it.  (I've only a copy I passed thru rplc,
which currently has a quite limited symbol table; consequently I had to
type in the words by address, as per the posting.)

A note to anyone using this:  I can only get this error to occur when
mixing metric and US units in one list, and the error only happens when
converting to a list, NEVER when converting to a single unit. 

I will look into thes further.  Perhaps using extended reals will alleviate
the problem, but that may make the code quite longer--I had hoped to make
this as small and unassuming as I could.
