> so, the right way to do what I want is something like sed 's/ \{1,\}/ /'
or 's/ */ /' (that is <space><space><space><star>)
(i.e. two spaces followed by 0 or more spaces).
or 's/ */ /' (<space><space><star>) which is the same outcome but less
efficient (because unlike the previous two versions this will match and replace
single space characters).
or or 's/ +/ /' in other applications (such as perl) that use egrep-like REs.
Gotta love REs!
