bug#1119: elisp-index-search on current symbol

[xah lee]

2 suggestions related to documentation lookup.

(1) have elisp-index-search's default prompt to be the symbol under  
cursor. This seems useful and consistent with other emacs lookup  
commands.

(2) have describe-function display a link to the elisp manual.

For (1), few people have suggested implementations here:
