Excellent stuff :-) I was just struck by the same thing myself a day
ago, but hadn't bothered solving it.
I replaced "gawk" with "awk", and then by a couple of invocations of
cut ... and then, seeing as you're using GNU ls, I cheated with the
--time-style to replace the whole line with
candidate=$(ls -lh --time-style + $candidate | cut -d' ' -f9)
On my Ubuntu 6.06 server machine, for vi I get ...
$ ./whichreally vi
