I agree than dwim would be better.  But what a hint to use for deciding
on showing a commit by sha instead of matching it in the commit messages?

Making the choice whether the word is hexinumeric doesn't look too
unambiguous.  What if the user wants to search a hexinumeric word
in the text of commit messages?  For example, searching for "5761a1a393"
to find messages that contain "Revert commit 5761a1a393 ..."
