Backport upstream commit cce141c42740f122dd8486ae04e21c2a81016ba8
to fix CVE-2026-57456: possible code execution with python complete
via crafted docstrings.
The fix replaces unsafe triple-quote string concatenation with
repr() in python3complete.vim and pythoncomplete.vim to properly
sanitize docstrings before exec(). A new test file adapted for
vim 8.0 is included to verify the fix.
