The `LF` after the command is optional (it used to be required). Note
that for reasons of backward compatibility, if the commit ends with a
-`data` command (i.e. it has has no `from`, `merge`, `filemodify`,
+`data` command (i.e. it has no `from`, `merge`, `filemodify`,
`filedelete`, `filecopy`, `filerename`, `filedeleteall` or
`notemodify` commands) then two `LF` commands may appear at the end of
the command instead of just one.
