[PATCH 7/7] worktree: document `list` verbose and prunable annotations

[Rafael Silva <rafaeloliveira.cs@gmail.com>]

Update the documentation with "git worktree list" verbose mode, prunable
and locked annotations for the default and porcelain format as part of
teaching the command to show prunable working trees and verbose mode.

 Porcelain Format
 ~~~~~~~~~~~~~~~~
 The porcelain format has a line per attribute.  Attributes are listed with a
 label and value separated by a single space.  Boolean attributes (like `bare`
 and `detached`) are listed as a label only, and are present only
 if the value is true.  The first attribute of a working tree is always
-`worktree`, an empty line indicates the end of the record.  For example:
+`worktree`, an empty line indicates the end of the record.
++
+In case any of the working trees are locked or is a candidate for pruning
+(See DESCRIPTION above) the labels "locked" and "prunable" is also shown
+followed by a reason, if available, otherwise only the labels are listed.
+For example:
