tests: demonstrate bug in `hg fix` with incorrectly dirty working copy If the parent commit needs formatting but the working copy already has the correct formatting, then the working copy will be reported as modified even though it's clean (because the size in the dirstate is incorrect). Because the bug only occurs when the size changes, I modified the formatter used in the test case to remove repeated spaces. Differential Revision: https://phab.mercurial-scm.org/D11208

typing: convert an annotation to an assertion in commands.py Pytype was happy with the annotation at one point, but 2021.04.15 now complains. Differential Revision: https://phab.mercurial-scm.org/D11206

test: remove `sleep` usage in `test-nointerrupt.t` (issue6271) We move from sleep based synchronisation to file creation based synchronisation. Sleeps is the path to the dark side. Sleeps leads to flakiness. Flakiness leads to anger. Anger leads to hate. Hate leads to suffering. Differential Revision: https://phab.mercurial-scm.org/D11205
