The fix for gh-92081 (gh-92281) was unfortunately flawed, and broke whitespace handling for encoded word patterns that had previously been working correctly but had no corresponding tests, unfortunately in a way that made the resulting headers not RFC compliant, in such a way that Yahoo started rejecting the resulting emails.  This fix was released in 3.14 alpha 1, 3.13 beta 2 and 3.12.5.   This PR fixes the original problem in a way that does not break anything, and in fact fixes a small pre-existing bug (a spurious whitespace after the ':' of the header label if the header value is immediately wrapped on to the next line).  (RDM)

os.path.exists() always returns False for it, and tempfile.mktemp() can
return a name that matches an existing named pipe.

different names until it completes successfully.

gh-143650: Fix importlib race condition on import failure (GH-143651)

Fix a race condition where a thread could receive a partially-initialized
module when another thread's import fails. The race occurs when:

1. Thread 1 starts importing, adds module to sys.modules
2. Thread 2 sees the module in sys.modules via the fast path
3. Thread 1's import fails, removes module from sys.modules
4. Thread 2 returns a stale module reference not in sys.modules

The fix adds verification after the "skip lock" optimization in both Python
and C code paths to check if the module is still in sys.modules. If the
module was removed (due to import failure), we retry the import so the
caller receives the actual exception from the import failure rather than
a stale module reference.

The code in test_makefile was attempting to ignore any
non-interesting files, but missed some corners:

1. There is never a *file* called `__pycache__`.
2. A directory containing only a `__pycache__` subdirectory should be
   ignored.
3. A directory containing only hidden files should be ignored.

Simplify this all into a couple of filters that let us check for empty
lists.
