Displaying template "file_copies" keyword without --copies

[Patrick Mézard]

As suggested in http://www.selenic.com/pipermail/mercurial-devel/2009-November/017148.html , I have a local patch which forces a template or style containing the {file_copies} keyword to always display it instead of doing so only if --copies is passed. The remaining failing test is:

-------------------------

This test compares the output of the default changelog and the styled one with a normal, --verbose and --debug output. With my patch, both --verbose and --debug differ because the related styles contain {file_copies} so the copies are displayed even if --copies is not set in the test. What should I do about it ?

1- Accept the styled changelog outputs are now equivalent only to the --copies non-styled ones?
2- Remove the {file_copies} from the styles so they match their non --copies counterpart?
3- Give up for this is not a tolerable compatibility breakage?
