[arch-dev-public] doc size

[Xavier]

Hello,

I like this gnome feature that warns me about running out of space and
proposes me to run a disk usage analyzer (baobab).
Looking at the results, I found out that /usr/share/doc was taking a
non negligible space : 140M
It's actually the 3rd biggest directory in my filesystem after two
games (openarena and flightgear). Well maybe 4th if I also count
warsow in /opt :)

It's especially gtkmm that made me go wtf. It takes 48MB. I checked
the package size, 60MB.
The next entries are far away, at 10MB, but still. Compared to the
package size, they can still be pretty big (more than half).
That made me want to check the proportion of docs in each package, and
I quickly hacked a script together.
I am pretty sure this subject has come here before, but I don't
remember seeing any results, so I will post them here.
That might help to establish some reasonable limits for when a package
should be split. And with makepkg supporting that now, it's much
better than before.
