[pca] enhancement request

Hi Jan,

I understand that - I try to avoid using interactive MOS as far as possible as 
well :)

I agree, this might be unexpected, and I actually don't remember whether I chose 
this behaviour to conform with -l and -d, or whether it was a user request. ISTR 
that somebody asked for a simple way to grep through the READMEs of one patch 
and all its required patches.

Not wrong, you just didn't notice that you can use "pca --nodep --readme ..." to 
get the behaviour you want. With all those options in PCA that's understandable, 
though :)

Maybe it would be more obvious to make --readme behave like you want it, but as 
there is no counterpart to --nodep to force dependency checking, it's easier to 
stick to the current behaviour. You can use a shell alias or script if you don't 
want to type the extra option everytime.

hth,
Martin.
