+Subject: [PATCH] depmod: do not output .bin to stdout
+
+index_write() relies on fseek/ftell to manage the position to which we
+are write and thus needs the file stream to support it.
+
+Right now when trying to write the index to stdout we fail with:
+
+	depmod: tools/depmod.c:416: index_write: Assertion `initial_offset >= 0' failed.
+	Aborted (core dumped)
+
+We have no interest in outputting our index to stdout, so just skip it
+like is done with other indexes.
+
+While at it, add/remove some newlines to improve readability.
