Hmph, interesting point.  Indeed, date.c::show_date_normal() decides
to hide the year portion if the timestamp and the current time share
the same year, so on Thu Jan 3rd, an attempt to show a commit made
on Mon Dec 31st of the same week would end up showing the year, so
yes, I agree with you that the above would break.

+TODAY_REGEX='5 hours ago'
+THIS_YEAR_REGEX='[A-Z][a-z][a-z] [A-Z][a-z][a-z] [0-9]* [012][0-9]:[0-6][0-9]'
+MORE_THAN_A_YEAR_REGEX='[A-Z][a-z][a-z] [A-Z][a-z][a-z] [0-9]* [0-9][0-9][0-9][0-9]'
