pager: drop the support for 'pager.enable=<bool>' This option was never released except for a release candidate. Dropping compatibility with this option will free the 'pager.enable' config option for other usage in the future.

pager: rename 'pager.enable' to 'ui.paginate' This aligns with what we do for color (see 7fec37746417). Pager is a central enough notion that having the master config in the [ui] section makes senses. It will helps with consistency, discoverability. It will also help having a simple and clear example hgrc mentioning pager. The previous form of the option had never been released in a non-rc version but we keep it around for convenience. If both are set, 'ui.pager' take priority.

color: special case 'always' in 'ui.color' This lift the confusing case, where 'ui.color=always' would actually not always use color.

color: turn 'ui.color' into a boolean (auto or off) Previously, 'ui.color=yes' meant "always show color", While "ui.color=auto" meant "use color automatically when it appears sensible". This feels problematic to some people because if an administrator has disabled color with "ui.color=off", and a user turn it back on using "color=on", it will get surprised (because it breaks their output when redirected to a file.) This patch changes ui.color=true to only move the default value of --color from "never" to "auto". I'm not really in favor of this changes as I suspect the above case will be pretty rare and I would rather keep the logic simpler. However, I'm providing this patch to help the 4.2 release in the case were others decide to make this changes. Users that want to force colors without specifying --color on the command line can use the 'ui.formatted' config knob, which had to be enabled in a handful of tests for this patch. Nice summary table (credit: Augie Fackler) That is, before this patch: +--------------------+--------------------+--------------------+ | | not a tty | a tty | | | --color not set | --color not set | | | | | +--------------------+--------------------+--------------------+ | [ui] | | | | color (not set) | no color | no color | | | | | +--------------------+--------------------+--------------------+ | [ui] | | | | color = auto | no color | color | | | | | +--------------------+--------------------+--------------------+ | [ui] | | | | color = yes | *color* | color | | | | | +--------------------+--------------------+--------------------+ | [ui] | | | | color = no | no color | no color | | | | | +--------------------+--------------------+--------------------+ (if --color is specified, it always clobbers the setting in [ui]) and after this patch: +--------------------+--------------------+--------------------+ | | not a tty | a tty | | | --color not set | --color not set | | | | | +--------------------+--------------------+--------------------+ | [ui] | | | | color (not set) | no color | no color | | | | | +--------------------+--------------------+--------------------+ | [ui] | | | | color = auto | no color | color | | | | | +--------------------+--------------------+--------------------+ | [ui] | | | | color = yes | *no color* | color | | | | | +--------------------+--------------------+--------------------+ | [ui] | | | | color = no | no color | no color | | | | | +--------------------+--------------------+--------------------+ (if --color is specified, it always clobbers the setting in [ui])

pager: document the 'pager.enable' option The 'config' helps was missing help about pager enabling/disabling.

pager: advertise the config option in the default hgrc Same as for 'ui.color', this is a critical part of the UI and we want user to find this config knob easily.

pager: document the 'pager' config section There as a 'hg help pager' section but the 'hg help config.pager' was missing.

pager: test the 'enable' config option While poking at this option I realised it was not tested.
