+scandir() returns "strings allocated via malloc(3)" which are then\r
+"collected in array namelist which is allocated via\r
+malloc(3)". Currently we just free the array namelist. Instead, free\r
+all the entries of namelist, and then free namelist.\r
+\r
+entry only points to elements of namelist, so we don't free it\r
+separately.\r

+\r
+This should fix a minor memory leak in notmuch-new. Please confirm I'm\r
+reading the manpage correctly ;)\r
