If the end of one enum is the `type' line for the next enum, we would
not notice it.

Fix this by reordering the code, and getting rid of the else: now if
the "we are within an enum" branch decides that it's the end of the
enum, it unsets $ei and we then immediately process the line as a "not
within an enum" line - ie as the start of the next one.
