bitrot in buildsym.c:start_subfile

[Doug Evans]

In buildsym.c there's this:

/* Start recording information about source code that came from an
   included (or otherwise merged-in) source file with a different
   name.  NAME is the name of the file (cannot be NULL), DIRNAME is
   the directory in which it resides (or NULL if not known).  */

void
start_subfile (char *name, char *dirname)
{


`name' cannot be NULL.

However, there's this:

  subfile->name = (name == NULL) ? NULL : savestring (name, strlen (name));

and this:

  if (subfile->name)

Am I missing something?
