py3: use '%d' for formatting a revnum in `hg co --date` code Differential Revision: https://phab.mercurial-scm.org/D7429

py3: send bytes from Rust-created warning patterns Python code expects bytes in both Python 2 and Python 3, so we should send bytes. Differential Revision: https://phab.mercurial-scm.org/D7454

py3: pass bytes to `configint` and `configbool` Both functions require bytes, even in Python 3. Differential Revision: https://phab.mercurial-scm.org/D7453

templates: make {indent("", " ")} be empty indent() is documented to indent all non-empty lines, but it made an exception for the first line, which always got indented. I also made indent() not indent the first line even if an indent override was given for the first line. I think that is what one would usually want.

tests: document behavior of indent() with empty first line indent() is documented to indent all non-empty lines, but it still indents the first line even if it's empty. Let's have tests for that. Differential Revision: https://phab.mercurial-scm.org/D7431

tests: check for Windows line endings We shouldn't generally be using Windows line endings in files under version control. I've accidentally committed a few files with Windows line endings recently. So let's add a test for this. Differential Revision: https://phab.mercurial-scm.org/D7448

tests: verify that Python scripts are blackened Scripts are Python too. They should be blackened. (As suggested by Pierre-Yves in D7420.) Differential Revision: https://phab.mercurial-scm.org/D7447

black: blacken scripts These scripts weren't blackened. I found these as part of adding script checking to test-check-format.t. # skip-blame black Differential Revision: https://phab.mercurial-scm.org/D7446
