[David Soria Parra]

New submission from David Soria Parra <dsp at php.net>:

The template is broken since version 1a85861f59af

the following templates doesn't work anymore, which breaks the Gource 
application:

$ cat gource.style
changeset = '{file_adds}{file_copies}{file_mods}{file_dels}'
file_mod  = "{date|hgdate}|{author|person}|M|{file_mod}\n"
file_add  = "{date|hgdate}|{author|person}|A|{file_add}\n"
file_del  = "{date|hgdate}|{author|person}|D|{file_del}\n"
file_copy = "{date|hgdate}|{author|person}|A|{name}\n"

$ hg log -r 0:tip --style gource.style
