largefiles: drop repo wrapping detection After 257afe5489d4 I see: $ hg id -q largefiles: repo method 'commit' appears to have already been wrapped by another extension: largefiles may behave incorrectly largefiles: repo method 'push' appears to have already been wrapped by another extension: largefiles may behave incorrectly be207d9b7e4b The warning is bad: * The message gives no hint what the problem is and how it can be resolved. The message is useless. * Largefiles do have its share of problems, but I don't think I ever have seen a problem where this warning would have helped. The 'may' in the warning seems like an exaggeration of the risk. Having largefiles enabled in combination with for instance mq, hggit and hgsubversion causes a warning (depending on the configuration order) but do not cause problems. Extensions might of course be incompatible, but they can be that in many other ways. The check and the message are incorrect. It would thus be better to remove the check and the warning completely. Before 257afe5489d4 the check always failed. That change made the check work more like intended ... but the intention was wrong. This change will thus also back that change out.

config: discard "%unset" values defined in the other files read in previously Before this patch, "%unset" can't unset values defined in the other files read in previously, even though online help document says that it can. It can unset only values defined in the same configuration file. For example, the value defined in "~/.hgrc" can't be unset by "%unset" in ".hg/hgrc" of the repository. This patch records "%unset"-ed values in "config.parse()", and discards corresponding values in "config.update()".

tests: rename from test-config-case.t to test-config.t for centralization Before this patch, there is no test script testing configuration handling generally. "test-config-case.t" seems to be specific for testing case sensitive configuration. This patch renames from "test-config-case.t" to "test-config.t" for centralization of tests around configuration handling.

i18n: show the non-ASCII password prompt text correctly Before this patch, the prompt text for asking password is directly passed to "getpass.getpass()" of Python standard library. In "getpass.getpass()" implementation on Windows environment, the prompt text is split into byte sequence and "msvcrt.putch()" is applied on each bytes in it. This splitting causes non-ASCII prompt text to be broken. This patch shows the prompt text for asking password on "ui.getpass()" side, and invokes "getpass.getpass()" with empty prompt text. This prevents non-ASCII prompt text from being broken in "getpass.getpass()" implementation. This patch also sets "ui.prompt" label to prompt text to follow "ui.prompt()" style.
