Allow installation via Meson

Fix merge_patch shadow warning

	Fix issue #1340.

        The eofbit is set manually since we don't go through the
	stream interface. We could maybe use the stream interface
	instead, but there are some assumptions regarding which
	exception go through, so this seems to be the most prudent
	approach for now.

Avoid shadowing a member of `this` by choosing the same name as
parameter (`-Wshadow`). Instead, make name of parameter more
expressive.
