Junio C Hamano 33e0f62ba9 pathspec: rename per-item field has_wildcard to use_wildcard
As the point of the last change is to allow use of strings as
literals no matter what characters are in them, "has_wildcard"
does not match what we use this field for anymore.

It is used to decide if the wildcard matching should be used, so
rename it to match the usage better.
