The original script (collection) has a config file where $FILE_EXTS is defined. However, we hardcode this to C and header files only.

Instead we use $tmpout (the uncrustify output), which has a well defined (no need to being escaped) filename. The file contents we diff from stdin has changed as well. It is no longer the uncrustify output, but instead the file contents from the index (staged), thus the --- and +++ lines, we need to fix, switched as well. Hope that explains it.

[Openvpn-devel] [PATCH] pre-commit: uncrustify based on staged changes
Previously the generated patch was based on the file(s) in the working directory. This is a problem if you have not to be commited changes there and these changes fix formatting issues that exist in the staging area. This effectively circumventes the script from rejecting the commit. An example: git add file.c git commit ... pre-commit hooks complains about formatting ... ... you fix the file manually, forget to git add ... git commit ... succeeds, even though the commit still has issues ...
