filecache: use bytes wherever possible in the tests This is closer than the actual usage, so I figured in would not hurt.

cachestat: avoid creating cachestat for http path The statichttprepo repo attemp to create cachestat for content we access through http. We modify the couple of place create cachestat object to detect this situation and avoids it. This is not marvelous, but there is few of them and the freeze is looming. This helps on Windows where calling cachestat on http path might create issues.

filecache: use binary path in the test This was overlooked when converting string. This is needed as we are about to introduce bytes specific code in the filecache code path.

branching: merge stable into default

py-3-13: stabilize the docstring output across all supported Python versions Python 3.13 now trims indents from docstrings at compilation time (to save space in .pyc), so all of our helptext is affected. The indentation has never served a user-facing purpose and was more here because nobody cared enough to remove it: we gain some screen space this way. Rather than undo the transformation (which isn't really possible since the transform also deletes leading/trailing whitespace), we align the behavior of older Python versions with that of 3.13. Unfortunately, this means breaking some of the translations. I've only touched the ones that need to work for some tooling tests to pass, but I do not have the time to fix the rest of them across all languages, since they cannot be done in an automated way. i18n updates have been basically abandonned for a good while now, hopefully someone cares enough to bring them back.

docstring: backed out changeset 51057ab0dffa In retrospect this is too much of a behavior change for stable. So I grafted the same change as 31076a2301f1 on default, and I am backing out its version on stable.

tests: stabilize `test-clonebundles-autogen.t` on Windows The problem was that the commands are spun up with `shell=True`, which uses `cmd.exe`, which doesn't understand `$foo` style variables. The HGCB variable expansion has to be delayed, because it's figured out right before launching the command. We could probably add a conditional for Windows, and rewrite the config to use `%foo%` style variables, but it's more maintainable to just wrap the command in a bash shell invocation. The forward style slashes in the path are needed to avoid accruing double backslashes (when switching between shells- the url template seems fine). Also need to strong quote the command so that the double quotes don't get stripped off of `$HGCB_BUNDLE_PATH`, which results in: sh: 1: Syntax error: Unterminated quoted string abort: command returned status 2: sh -c "cp $HGCB_BUNDLE_PATH $TESTTMP/final-upload/"
