On the one hand this is low-level detail. On the other, it is 
user-visible detail, e.g., when I use dired or 'ls' on a directory I'll 
see the symlinks. So I'd be mildly inclined to see a brief mention in 
the user manual with details as necessary in the elisp manual. The user 
manual could say something simple like 'lock files are directory entries 
whose names begin with ".#"'. If more details are needed, they could be 
in the elisp manual (e.g., MS-Windows lock names are independent of lock 
names of other systems).
