Clang-Format removes empty line at end of file

[GeorgWeinhold]

For C and C++ an empty line at the end of each file (header and implementation) is mandatory.

clang format does not add this new line. Moreover, clang-format removes existing empty line at the and of files.

This leads to compiler warnings.

Can you give a reproducer in which clang-format removes the existing empty line, please?
