clonebundles: move the manifest reading in a dedicated function We are about to make the logic more advanced to help hosting solution, so we need to centralize it first.

doc: format argument for date uses strftime format string (issue6818)

clonebundles: filter out invalid schemes instead of failing on them Previously, an invalid clonebundle scheme would result in a failed clone. By specifying a list of schemes we support, we can make sure adding a new scheme (like the one for inline clonebundles) does not result in clones failing for older clients.

clonebundles: demonstrate bad behaviour when unknown scheme is present

rhg: support `rhg files` with `ui.relative-paths=false`

rhg: make `rhg files` work if `ui.relative-files=true` is specified

rhg: test `rhg files --config ui.relative-paths ...` Add some tests. All of these are falling back for now, will be fixed in follow-up commits.

cleanup: simplify code

dirstate: better error messages when dirstate is corrupted The current error message "Overflow in dirstate" sounds confusing because it suggests either a certain size limit that's being exceeded, or integer arithmetic overflowing. The reality is just a file being shorter than expected.

rust: remove an unused error variant DirstateMapError::EmptyPath
