bug#19338: [PATCH 0/3] Implement an ElDoc function which describes char at point

[Michal Nazarewicz]

From: Michal Nazarewicz <mina86@mina86.com>

`describe-char-eldoc' displays information about character at point,
and can be used as a default value of `eldoc-documentation-function'.
It is useful when, for example, one needs to distinguish various
spaces (e.g. ] [, ] [, ] [, etc.) while using mono-spaced font.

Michal Nazarewicz (3):
  eldoc: use default eldoc function if local one gives no results
  descr-text: add `describe-char-eldoc' describing character at point
  eldoc: convert `eldoc-documentation-function' into a defcustom
