Yes, of course.  This is our internal jargon word, for saying that nothing 
really significant has changed.  (No semantic change, no real structural 
change.)  This is important information.

A better counter example is "fixed bug", because it looks like it 
addresses a significant issue without saying what it was.  (And very often 
a perceived "bug" is actually an important feature.)  Just a few days ago 
I was again standing before an ancient changeset that claimed to have 
fixed a bug, but it was otherwise unclear. So I had to guess at the 
greater context.  Luckily such bad log entries are relatively rare.
