bug#14928: 24.3.50; Apropos GNU ELPA's all.el and occur-edit-mode

[Jambunathan K]

Based on a *cursory* look, GNU ELPA's all.el and occur-edit-mode seem to
offer similar functionality.

In that case,

1. Remove all.el from GNU ELPA, possibly after moving over missing
   features to occur-edit-mode.

2. In `occur-edit-mode' make killing of matched line easier and more
   intuitive.  Currently, I have to
   
   - C-a to the beginning of line
   - Position the cursor *past* the line number
   - C-k it.

   There should be a easy way to handle it.

3. Document `occur-edit-mode' in the Info manual.  This seems like a
   pretty useful feature.
