Aside from the historical regex parsers why do we have any space
indenting in the planet.osm file? In the first planet file I found on
my filesystem (late July) it has 110478125 lines, at a guesstimate
average of 4 bytes indenting per line that's 441912500 bytes of wasted
It would be a nice task to write a simple tool that stripped the
indenting and new lines from the most recent planet.osm file to allow
accurate comparison of file sizes. If I get time I'll try and do this
in the next couple of days - unless someone beats me to it.
