Hello,

Thank you for the PR. It looks like this PR mixes a few different kinds of changes.

What does this optimize:

diff --git a/src/main/java/org/apache/commons/io/filefilter/DelegateFileFilter.java b/src/main/java/org/apache/commons/io/filefilter/DelegateFileFilter.java
index a4fdc74..b5163da 100644
--- a/src/main/java/org/apache/commons/io/filefilter/DelegateFileFilter.java
+++ b/src/main/java/org/apache/commons/io/filefilter/DelegateFileFilter.java
@@ -74,9 +74,8 @@ public DelegateFileFilter(final FileFilter filter) {
public boolean accept(final File file) {
if (fileFilter != null) {
return fileFilter.accept(file);

•    } else {
  

•        return super.accept(file);
   }
  

•    return super.accept(file);
  

  }

?

I usually make changes like the above as well but I would not consider them "optimizations". This kind of change (to me) makes the code more readable.

Perhaps you can explain what you mean by optimization? I usually think of performance, speed or memory.
