yeah, i'm fairly certain that my system isn't broken re: $IFS, turns out that
i hadn't fully understood that the default for grep was to use 'basic'
regular expressions but the script i was telling you about aliased grep with
'egrep' which apparently treats ()s as special characters, and these were in
all the patterns that i was having problems with! the presence of spaces
seems to be a red herring! :-)
