patch: date formats

[Martin Renold]

Hi,

This patch makes cvs understand dates like "DD.MM.YYYY" (the one we learn
in school here), and additionally "two days ago" (instead of 
"2 days ago").

I could not figure out how to make "DD.MM. HH:MM"  working cleanly,
because the parser overlooks the space and thinks HH is the year. I tried
a new token tUNUMBER_DOT but it messed the whole thing up and I reversed
those changes.

By the way, "15.5.03" will not work as expected, it's a y2k issue. The
best way would be to interprete two digit years between CURRENTYEAR - 49
and CURRENTYEAR + 50, but, well...

Please CC me any comments, I am not subscribed.

bye,
Martin
