* Why is there a `0' flag used with `%I' in asm_fprintf ?

Many uses of asm_fprintf in m68k.c and a few in m68hc11.c use the `0'
flag in conjunction with `%I' when calling asm_fprintf. Reading
through the function body of asm_fprintf in final.c, it appears that
the zero is consumed, but has no effect. I.e. `%0I' just spits out
IMMEDIATE_PREFIX unmodified as would plain `%I'.
So it seems harmless except for the fact that someone reading the code
in m68k.c might think the `0' flag is supposed to do something.
Should all instances of `%0I' be changed to `%I', or have I missed
something?
Thanks,

Assuming these are bogus, patch here:
