I'm using the -I option in gnu diff (on sparcs 4.1.2) and not sure what I'm seeing makes sense...

I have a script I'm using:
diff -W 160   -I '.*\+.*' --ignore-all-space --ignore-case --ignore-blank-lines  --side-by-side $* 

I want to ignore lines with spaces, number of spaces, and lines with a + in them.
I get:
ax=3ae8  bx=0000  cx=0000  dx=0000  sp=ffff  bp=0000  si=0000  di=0000          ax=3ae8  bx=0000  cx=0000 dx=0000 sp=ffff bp=0000 si=0000 di=0000
cs=3ae8  ds=8000  ss=8000  es=8000  ip=00a8  o=0 d=0 i=1 s=0 z=0 a=0 p=0 c=0    cs=3ae8 ds=8000 ss=8000 es=8000 ip=00a8  o=0 d=0 i=1 s=0 z=0 a=0 p=0 c=0
test_inc_+89         mov     ss,ax                                            |

Which indicates the line beginning test_inc_ is being diffed...which I don't want it to be...

I ran this with egrep and it seemed to do what I wanted...
