#3064: Implement "show" menu to list various internal configs as a nicely paged menu
Running ':attachments ?' in mutt shows current attachment settings on stdout instead of inside mutt... which is ugly. The attached patch implements a "show" menu with a few "demo" views to show what this can be used for: * show attachments: Replacement for "attachments ?" (latter kept for compatibility) * show config [regex]: Show all config options matching regex (if omitted, regex defaults to ".", i.e. all) * show mailboxes: Show all known mailboxes in order they were defined * show spam: Show all currently configures spam recognition commands Except "config" these don't seem to be extremely useful. However, what comes to mind and why I took the prototype this far is to mostly prepare the code to be ready to implement this for hooks. For example, 'show folder-hook [folder-regex]' would be nice to have to know what folder- hooks mutt would execute in what order. -- Ticket URL: <http://dev.mutt.org/trac/ticket/3064>
