\*picky\* I find it often works better to wrap `unwind-protect` in a macro.
Example usage
```
(clang-format--with-delete-files-guard files-to-delete
... snip ...
(push (setq tmpfile-curbuf (make-temp-file "clang-format-vc-tmp"))
temp-files)
(push tmpfile-curbuf temp-files))

Here is a macro that does this:
```
(defmacro clang-format--with-advice (bind-files-to-delete &rest body)
"Execute BODY which may add temp files to BIND-FILES-TO-DELETE."
(declare (indent 1))
`(let ((,bind-files-to-delete nil))

,@body)
(while ,bind-files-to-delete
(with-demoted-errors "failed to remove file: %S"
(delete-file (pop ,bind-files-to-delete)))))))
