What I mean when I say I want exposure comp in manual mode is the following: Say I want to shoot at F2.0, T=1/60s, and I am using AutoISO 1600. The camera exposes for the "correct" exposure as measured by the in camera meter, choosing ISO 800. I want to achieve the result of underexposing by one stop. My options are: (1) Use F/2.8; (2) Use T=1/120s; (3) cheat and use ISO 400 (nice not to have to change films to do this). In each case the result should be the same - I should record half the count from each pixel on the sensor. I want the option to stick with F/2.0, T=1/120s, and instead of fiddling around to set ISO=400, I just want to set EC=-1 and let the camera work out the required ISO setting to produce an image with half the count (i.e. exactly the same as darker by 1 stop) than its meters would normally achieve by choosing the ISO to give the "correct" exposure.This is what we are all meaning when we say we want EC to work in Manual Mode with AutoISO.

I'm not a Manual user. I normally use my X100 and X-Pro 1 in Auto-ISO mode, and never understood the issues people were having with the exposure compensation in manual mode. I always thought to myself, "If you want to underexpose by -2/3 of a stop, why don't people just adjust the shutter speed (or aperture) by -2/3 of a stop!?!"
After trying it out for myself, I now understand. With Auto-ISO turned on, even if you wanted to underexpose by reducing your shutter speed by 1 stop, the ISO would simply increase by 1 stop to compensate!
It's annoying, and now, I can see why so many people complain about it.
For me, not having a minimum shutter speed in Auto-ISO is a bigger issue, and I even believe that there should be a maximum shutter speed setting in order to force the ISO to automatically drop when the shutter speed is unnecessarily fast, but now I understand your pain.
