It's fine that "pkg-config --version" prints the version of pkg-config.

My complaint is that "pkg-config --version xyz" does the exact same 
thing, completely ignoring the "xyz"! I'm pretty certain the result is 
not what the user expects. It sure fooled me, I wasted a lot of time 
trying to figure out why all my attempts to install or compile a package 
refused to change the version number!

I had 0.26 so maybe they fixed that. I did not submit a bug report for 
that anyway.
