ignore: info/exclude should trump core.excludesfile

$GIT_DIR/info/exclude and core.excludesfile (which falls back to $XDG_HOME/git/ignore) are both ways to override the ignore pattern lists given by the project in .gitignore files. The former, which is per-repository personal preference, should take precedence over the latter, which is a personal preference default across different repositories that are accessed from that machine. The existing documentation also agrees. However, the precedence order was screwed up between these two from the very beginning when 896bdfa2 (add: Support specifying an excludes file with a configuration variable, 2007-02-27) introduced core.excludesfile variable.
