Trying to get at file copy info in hg log by using template {file_copies}

[John Rice]

Anyone any thoughts on how to get at the file copy information from a hg 
log command when using a template directive? Currently it barfs on me, 
see issue:

We need to try and get this sorted so we can display a nice Search 
History panel in the NetBeans IDE Mercurial plugin. I can run the hg log 
command twice and use the -C option without the template, but that would 
be slow and painful as I'd have to dig all the Copy info out of the raw 
output and merge it back into the template stuff :(
