OK, I see the problem on FreeBSD as well.

I'm not sure how it is supposed to work. A brief look shows that it
may have been intended that:
the loop in os_unix.c calls ui_inchar()
ui_inchar()
-> read_from_input_buf()
-> fill_input_buf()
checks for CTRL-C and sets got_int
So something in between stops this from happening.
If I do ":!cat" then typing CTRL-C does appear to work. Perhaps it's
the flood of output to the screen that stops the CTRL-C check? No time
to investigate further right now.
