tests: use ls -A instead of ls -1 in test-removeemptydirs.t In case the tests are run as root, ls assumes -A by default on some systems (e.g. NetBSD). Tests probably shouldn't be run as root, but let's use -A just in case, for convenience.

release: add the "6.3" to the 6.3 release The release was tagged "6.3.0" while the custom have been to omit the third ".0" for initial release for the history of the project. For consistency, we add the customary version of the tag to the 6.3 release.

tests: fix new git protocol policy in convert-git.t Recent versions of git restrict the use of the "file" protocol for security reasons (https://github.com/git/git/commit/a1d4f67). This broke this test, which failed with the following hidden error: "fatal: transport 'file' not allowed". This patch relaxes the git configuration for the test to solve this.

debug-delta-find: add a --source option This will help us to understand the delta-find operation in different situations.

demandimport: ensure lazyloaderex sets loader attributes (issue6725) Adds test capturing missed expectation.
