RE: feature request: indicator of minibuffer-recursion depth

[Drew Adams]

Seems fine (given Richard's decision to put the indicator in the
minibuffer). A minor mode for this is a good idea.

However, the particular indicator you use adds 17 characters to the
minibuffer text, which is often already very busy. Just the number itself
should be sufficient, perhaps followed by a separator such as `)'. IOW,
instead of

 Find file:
 (minibuf-depth 2) Match also (regexp):
 (minibuf-depth 3) Match also (regexp):

use just:

 Find file:
 2) Match also (regexp):
 3) Match also (regexp):

We could add an option whose value is the text to use, with default value
(format "%s)" (minibuffer-depth)).
