[argyllcms] logo2cgats -2

Hi Graeme,

I stumbled across an old bug in logo2cgats -- it seems to dislike the "-2" flag:

klaus:~ klaus$ curl -O http://www.color.org/FOGRA27L.txt
klaus:~ klaus$ logo2cgats -2 FOGRA27L.txt FOGRA27
Segmentation fault

since you didn't release v0.60 yet (although I told you to do so ;-) maybe this is an opportunity to fix it.

Attached you find some debugging info.

I hope this helps,

Klaus 
curl -O http://www.color.org/FOGRA27L.txt
logo2cgats -2 FOGRA27L.txt FOGRA27
Segmentation fault

(this also happens with argyll 0.53)
