bug#8538: 24.0.50; please index node `Coding Conventions' wrt file-name length

[Drew Adams]

Someone asked me the conventional limit on library file names.  I
thought it was 14 but wanted to be sure. I tried using the index in the
Elisp manual, but it was no help (AFAICT).  I ended up searching the
manual for "14" since I recalled that, and I eventually found it.
 
Please add some index entries to enable users to more easily locate this
convention.  Thx.
