pager: Add a configuration to enable/disable the pager for certain commands Add the configuration options pager.ignore and pager.attend. You can disable the pager on certain commands by adding them to the pager.ignore setting. To whitelist commands, you can add them to pager.attend. To disable or enable global commands like 'hg version' or 'hg help' you have to use your global .hgrc. (thanks, Matt Mackall)
