perf: omit copying from ui.ferr to ui.fout for Mercurial earlier than 1.9 Before this patch, referring ui.ferr prevents perf.py from measuring performance with Mercurial earlier than 1.9 (or 4e1ccd4c2b6d), because ui.ferr isn't available in such Mercurial, even though there are some code paths for Mercurial earlier than 1.9 in perf.py. For example, setting "_prereadsize" attribute in perfindex() and perfnodelookup() is effective only with hg earlier than 1.8 (or 61c9bc3da402).
