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.

== New Features ==

 * Windows will process hgrc files in %PROGRAMDATA%\Mercurial\hgrc.d.


== New Experimental Features ==


== Bug Fixes  ==

 * The `indent()` template function was documented to not indent empty lines,
   but it still indented the first line even if it was empty. It no longer does
   that.

== Backwards Compatibility Changes ==


== Internal API Changes ==

 * Matcher instances no longer have a `explicitdir` property. Consider
   rewriting your code to use `repo.wvfs.isdir()` and/or
   `ctx.hasdir()` instead. Also, the `traversedir` property is now
   also called when only `explicitdir` used to be called. That may
   mean that you can simply remove the use of `explicitdir` if you
   were already using `traversedir`.

 * The `revlog.nodemap` object have been merged into the `revlog.index` object.
   * `n in revlog.nodemap` becomes `revlog.index.has_node(n)`,
   * `revlog.nodemap[n]` becomes `revlog.index.rev(n)`,
   * `revlog.nodemap.get(n)` becomes `revlog.index.get_rev(n)`.

 * `copies.duplicatecopies()` was renamed to
   `copies.graftcopies()`. Its arguments changed from revision numbers
   to context objects. It also lost its `repo` and `skip` arguments
   (they should no longer be needed).
