GIT_ATTR_HAS_VALUE checks if an attribute is set to a value (as
opposed to TRUE, FALSE or UNSPECIFIED). This would be the case if
for a file with something like:
*.txt eol=lf
Given this, looking up "eol" for onefile.txt will give back the
string "lf" and GIT_ATTR_SET_TO_VALUE(attr) will return true.
