To remove unwanted spaces at the end of a (simple) string I use the
following routine.It would be easy to customize it to remove characters only
from the left or tight side.

-- "   this is a    "  becomes  "this is a"
global function remove_end_spaces(sequence word)
 integer a,b
 a=0
 b=length(word)
 if b then
  for i = 1 to b do
   if word[i]!=' ' then a=i exit end if
  end for
  if a then -- ok, at least one valid character detected
   for i = b to a by -1 do
    if word[i]!=' ' then b=i exit end if
   end for
   return word[a..b]
  end if
 end if
 return {}
 end function
