Subject: clang-format plugin: Add missing NL (new line) at EOF (end of file)
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=f87b529510cd26b9835cca8602a504985b773efb;p=clang

clang-format plugin: Add missing NL (new line) at EOF (end of file)

clang-format.exe removes trailing new lines at end of file.

However, if no NL is found at EOF one should be added.

Patch by Teodor MICU!
