Tracking the old and new sha might be difficult.
Amending changes the history of following commits too. ;)

Only changing the subdirs is easy and as this changes the history
anyway I used it to test what's possible with filter-branch as I
haven't played with it yet, i.e.:
- add a $fooproto prefix to the subject
- remove files we may delete later anyway
- sort files into specific directories (specs -> specs/$fooproto/...,
.h -> include/X11/{fonts,extensions,...}

Me too. And if the decision is to f*ck up the history, I contributed
an example howto do it the hard way. ;)
