bug#54030: 29.0.50; [PATCH] Extend bookmark menu with column displaying handler type

[Matthias Meulien]

This is a feature request.

Bookmarks handled by VC (through `vc-dir-bookmark-make-record') are
named after the VC directory prefixed by the name of the VC backend
(with parentheses).  Thus when one use a single VC backend, eg Git, all
bookmarks handled by VC start with "(Git) " which makes the sort of
bookmarks by name in bookmark menu useless.

I suggest to remove that prefix but extend the bookmark menu with a new
column "Type" displaying the type of bookmark handler.  As a result
sorting bookmarks by their name don't gather bookmarks handled by VC
anymore.

Example:

becomes with the proposed patches:

Patch are attached. Note that at present time there's no way to filter
bookmarks by type, but I may add this feature if people are interested.
