Unarchiving LhA archives with file comments appends comments to filenames

AmigaDOS allowed the attachment of an 80 character comment string to files, and 
LhA archives created on the Amiga include the comment in the filename array, 
separated with a NULL byte. The Unarchiver 3.7 appends the comment to the 
filename with a space, as opposed to commandline lha which silently discards 
the comment. I have attached cfd.lha which has comments attached to every 
filename, and here's a dump of the first file's header:

  .byte $57                                     ; Header length
  .byte $ba                                     ; Header checksum
  .byte $2d,$6c,$68,$35,$2d                     ; "-lh5-"
  .dword $00000550                              ; Compressed size
  .dword $0000069e                              ; Original size
  .dword $2c9383c4                              ; Date stamp
  .word $0000                                   ; Attributes/header level
  .byte $41                                     ; Pathname length
  .byte $63,$66,$64,$2e,$69,$6e,$66,$6f         ; "cfd.info"
  .byte $00                                     ; NULL
  .byte $45,$72,$73,$74,$65,$6c,$6c,$74,$20,$31 ; "Erstellt 1"
  .byte $39,$2e,$30,$34,$2e,$32,$30,$30,$32,$20 ; "9.04.2002 "
  .byte $31,$35,$3a,$35,$31,$3a,$31,$37,$2c,$20 ; "15:51:17, "
  .byte $6c,$65,$74,$7a,$74,$65,$72,$20,$5a,$75 ; "letzter Zu"
  .byte $67,$72,$69,$66,$66,$20,$30,$34,$2e,$30 ; "griff 04.0"
  .byte $32,$2e,$32,$30,$30,$39                 ; "2.2009"
  .word $8308                                   ; CRC16
