I am trying to use Champion and Blackman's nice bash script,
which I have appended below, to assign different date formats
according to the age of the date.
I have tested each of the conditionals of this script and
it seems to work from the shell. However when I try to use it
from the mutt command line, it sets the desired format ONLY
for the messages which are less than one day old. More accurately
it applies the "less-than-one-day-old" to ALL messages.
I'll appreciate any suggestion about what I am doing wrong.
