It is not 11+3, but 14 characters period.  (Which would map to 11+2 anyway,
including the period).

No, primarily s5 file systems.  BSD or SVR4 'ufs' file systems support up
to 255 character filenames.  It is not related to the actual UNIX revision
so much as the file system type itself.  For example, SVR4 UNIX still has
14 character filename limits for s5 file systems, which it must for 
compatibility reasons.
