fopen(3) returns NULL in case it can't open the STREAM.
fgetln(3) returns NULL if it can't get a line from a STREAM.
malloc returns NULL if it can't allocate memory.

Rename usr.sbin/mtree to usr.sbin/fmtree since it is not what /usr/sbin/mtree
actually is (which is usr.sbin/nmtree).

Remove clause 3 in the copyrights (according to permission in src/COPYRIGHT)
Remove trailing whitespace.

Use __FBSDID over rcsid[]. Protect copyright[] where needed.
