Raise an ArgumentError when the same subparser name is added twice to an
ArgumentParser. This is consistent with the (default) behavior when the
same option string is added twice to an ArgumentParser.
(Support for `conflict_handler="resolve"` could be considered as a
followup feature, although real use cases seem even rarer than
"resolve"ing option-strings.)

Fixed few typos and enhanced few paragraphs for your review and consideration.
Trivial contribution towards continuous improvement, so no issue was raised.

#85757https://docs.python.org/3/tutorial/datastructures.html#nested-list-comprehensions
I do think this is clearer, but I wonder if 'nested' should be kept though to get the terminology out there more often. So perhaps it could be something like 'inner (nested) listcomp' or 'nested (inner) listcomp' despite sounding a bit redundant

example.com is reserved by the IANA as special-use domain name for documentation
purposes. The domain names are used widely in books, tutorials, sample network
configurations, and generally as examples for the use of domain name.
On the other hand, mydomain.com is real Domain Name Registration service.
* Check the types of PRECALL_METHOD_DESCRIPTOR_FAST_WITH_KEYWORDS

It was raised if the charset itself contains characters not encodable
in UTF-8 (in particular \udcxx characters representing non-decodable
bytes in the source).
Only sequence of ASCII digits will be accepted as a numerical reference.
The group name in bytes patterns and replacement strings could only
contain ASCII letters and digits and underscore.
This gets all the major items in #91491. However, I didn't get around to
adding what's new entries for the large clump of changes in the last
bullet point in the issue.

Also updated `make -C htmlview` so it used a full path with `file://`, because the original didn't open the page (macOS).
For example:
```sh
cd Doc
# Doesn't open anything:
python3 -c "import webbrowser; webbrowser.open('build/html/index.html')"
# Opens the docs page e.g. file:///Users/hugo/github/cpython/Doc/build/html/index.html :
python3 -c "import os, webbrowser; webbrowser.open('file://' + os.path.realpath('build/html/index.html'))"
```

`HOSTRUNNER` is a program which can be used to run `BUILDPYTHON` for the host platform (for example, `python.js` requires `node`).
Also change depedencies from `build_all` to `all` so that targets which can't build everything (e.g. WASM) can still run `buildbottest` and `pythoninfo`.

When Python is built with "./configure --enable-pystats" (if the
Py_STATS macro is defined), the _Py_GetSpecializationStats() function
must be exported, since it's used by the _opcode extension which is
built as a shared library.
