pager: add tests We've never had tests for pager, and I want to start experimenting with ways to clean up the implementation and make it a bit more graceful.

tests: flag Windows specific lines about background closing as optional

run-tests: defer leftover (?) cleanup until after all output is exhausted Previously, after matching a single line, any contiguous subsequent lines ending with (?) would be added to the output and removed from the expected output. This is a problem if the subsequent test output would have matched the consumed (?) line, because it kept the optional line and then added a duplicate without the (?) [1]. Instead, wait until there is nothing more to match before handling the leftovers. [1] https://www.mercurial-scm.org/pipermail/mercurial-devel/2016-February/080197.html

test-run-tests: pad the failure test to preserve the run order Test size seems to dictate the order in which the tests are run, and the next patch will add to test-success.t.

changelog: backed out changeset 86de91c56355

changelog: backed out changeset 1778770e1982 We want to avoid leaking UTF-8 to main body of code wherever possible.

dispatch: store norepo/optionalrepo/inferrepo attributes in function (API) This can eliminate import cycles and ugly push/pop of global variables at _checkshellalias(). Attributes of aliascmd are directly accessible. Because norepo/optionalrepo/inferrepo lists aren't populated, extensions examining them no longer work. That's why this patch removes these lists to signal the API incompatibility. This breaks 3rd-party extensions that are yet to be ported to @command decorator.

extensions: copy extra __dict__ of original function Future patches will make @command decorator set properties such as "norepo" to a function object. This patch makes sure these properties never be lost by wrapcommand() or wrapfunction(). This change won't be crazy as the standard functools.wraps() copies __dict__.

extensions: copy attributes to wrapper by wrapfunction() Before this patch, new partial function "wrap" had no useful docstring. It makes sense to copy __doc__ and __module__ as we do for wrapcommand().

extensions: extract function that copies function attributes to wrapper wrapfunction() will be changed to copy these attributes. See the next patch for details.
