Simple list problem that's defeating me!

[Neil Webster]

Thanks for the help so far.

The background to the problem is that the lists come from reading a
dbf file.  The code that I am trying to write is to merge lines of the
dbf based on the first column.  So in my example there would be three
lines:
a 2 3 4
b 10 11 12
a 2 3 4

The expected output from the above example lines would be:
a 4 6 8
b 10 11 12

 ... and the lines are read as: [[a,2,3,4],[b,10,11,12], [a,2,3,4]]

In response to not posting working code or actual inputs, ummm, that's
why I am asking the question here.
