Personally I think this is an adoption blocker. On large trees it's
very useful to be able to say "show the log entries that touch this
file/directory tree". Performance would be nice, but the functionality
is key IMHO.

Equally useful is being able to generate a log that includes the diff,
this makes it easy to search for a certain addition/removal of code
and easily identify which change caused it. Obviously you need to do
something intelligent WRT merges.

There needs to be a way to get the diff between a revisionid and it's
parent* without any extra fuss, ie:
  bzr diff -r revid:michael at ellerman.id.au-20060722073445-c88ec248ad3f4799

* Obviously merges make this harder, but you can just pick one parent
and have a flag to change which one is used.

I realise the best way to get that all supported is to write it myself :)
