How to add increasing counter for cells containing same text?

If I have a column with a repetitive series of text items, how can I get a counter that shows the number of times that text has already shown up?

I.e. How can I get this?

A	1
A	2
B	1
C	1
A	3
B	2

I think a COUNTIF() with a mix of absolute for the beginning of the address and relative for the end, and copying down.
