Is this a genuine bug or am I misusing awk somehow?

You are supposed to set FS before awk reads and tries to parse the line; in
this case, that means setting it in the BEGIN block or on the command line
with -v.

This is documented in the gawk manual, see


the box titled "changing FS does not affect the fields".

Doh! Thank you Davide. I can hardly believe I missed that. Works perfectly now. Yay! I'm very grateful.

If you don't have any failures then you're not trying hard enough.
