What a Windows editor saves, and a standard user's Windows install (from dev 9d6f66456a3d)

- CRLF line endings are read as newlines on every system (the reader used
  to delete the pair, collapsing a Notepad++ file into one line on Linux
  and macOS); a leading UTF-8 byte-order mark is ignored; a UTF-16 or
  Windows-1252 source is refused with the encoding, the place and the
  remedy named. .gitattributes pins LF in every clone.
- Windows source install: the repository path must hold no space (GNU
  Make), accented letters are fine (every linker input is relative now);
  python.org's Python is selected ahead of an MSYS2 one that poppler pulls
  in; TeX Live goes to its Windows default C:\texlive\2026.
- The Python binding needs an ASCII installation path on Windows, and its
  suite says so there.
