* dired.c (NAMLEN): Never use d_nameln to get the length of the

Browse source 
directory entry's name; it is used inconsistently.  Always call
	strlen instead.

/* The d_nameln member of a struct dirent includes the '\0' character
on some systems, but not on others. What's worse, you can't tell
at compile-time which one it will be, since it really depends on
the sort of system providing the filesystem you're reading from,
not the system you are running on. Paul Eggert
<eggert@bi.twinsun.com> says this occurs when Emacs is running on a
SunOS 4.1.2 host, reading a directory that is remote-mounted from a
Solaris 2.1 host and is in a native Solaris 2.1 filesystem.
Since applying strlen to the name always works, we'll just do that. */
