well. i think that we can distribute of pca output into following
piesces:

1) stdout << normal output like list of patches & etc
2) stderr:
	2.1) headers which could be maintained by -H switch
	2.2) --debug messages which should be printed on stderr anyway

but its only my proposal ;) .. 

ad.1) i cant see anything useful that in current one are headers printed
on stdout
ad.2) to your mention about *small *disadvantage: what about to add
there a switch, which allows to save --debug into file, like

--debug=$file and if $file not specified, stderr is taken by default ?
