[PATCH] Improve default mouse menu for mode from modeline

[pierre.techoueyres@free.fr (Pierre Téchoueyres)]

[-- Attachment #1: Type: text/plain, Size: 836 bytes --]

Hello emacs's developpers,

I would submit an enhacement for when you use the mouse to display the
menu for a mode (major or minor) from the modeline.


For now, if the mode doesn't define a custom mouse menu, the menu title
simply display the mode indicator. But sometimes this indicator isn't
really obvious.

The attached patch try to improve this by appending the full mode name
after the indicator.

For example the Smartparens minor mode has 'SP' as indicator. So his
menu is look like:
---------------------
| SP
---------------------
| Turn off minor mode
| Help for minor mode
----------------------

Whit the attached patch the menu will look like:

------------------------
| SP - Smartparens Mode
------------------------
| Turn off minor mode
| Help for minor mode
------------------------

Hope this could help.

Pierre.

Subject: [PATCH] 'minor-mode-menu-from-indicator' now display full minor mode.

When there is no menu for a mode, display the mode name after the
indicator instead of just the indicator (which is sometime cryptic).
Ex:
before : SP
now    : SP - Smartparens Mode

* etc/NEWS: Add en entry for this new feature.
* lisp/mouse.el (minor-mode-menu-from-indicator): Append the mode name
  after the indicator when there is no menu defined by the mode.
