Shell commands

1. openstreetmap.org changeset download + timing
   http://www.openstreetmap.org/api/0.6/changeset/#id/download -> cs-#id.osc

   LC_ALL=C curl -s -o "cs-#1.osc" -w '| %{filename_effective} | %{size_download} bytes | %{time_starttransfer} s | %{time_total} s |\n' "http://www.openstreetmap.org/api/0.6/changeset/{45229331,45018920,45031863,45656403,46858895,44989548,46988696,46552513,45488240,45489434,45064759,45639229,45579952}/download"
   

2. create adiff id-filter query (.ql) from Changeset download (.osc)
   cs-#id.osc -> cs-#id.ql
   Uses first (minus one second) and last edit timestamps instead of changeset meta start/end timestamps.
