color: move git-subrepo support into the subrepo module Now that all ui instance carry a '_colormode' attribute, we can access and comply to it directly in the subrepo code. The actual implementation could probably be a bit smarter, but we stick close to the current one for the sake of simplicity.

color: move 'modesetup' into the core module Yet another piece of code moving from the extensions to the module in core!

color: move 'terminfosetup' into the core module Another step closer to have all the logic living in core

subrepo: run the repo decoders when archiving The decoders were already run by default for the main repo, so this seemed like an oversight. The extdiff extension has been using 'archive' since 68822b7cdd01 to support -S, and a colleague noticed that after diffing, making changes, and closing it, the line endings were wrong for the diff-tool modified files in the subrepository. (Files in the parent repo were correct, with the same .hgeol settings.) The editor (Visual Studio in this case) reloads the file, but doesn't notice the EOL change. It still adds new lines with the original EOL setting, and the file ends up inconsistent. Without this change, the first file `cat`d in the test prints '\r (esc)' EOL, but the second doesn't on Windows or Linux.

wix: include the help for pager Similar (I assume) to 65d2538ac993.

manifest: check 'if x is None' instead of 'if not x' The old code here would end up executing __len__ on a tree manifest to determine if 'not _data' was true or not. This was very expensive on large repos. Since this function just cares about memoization, we can just check 'if _data is None' instead and save a bunch of time.
