Subject: Add notice about empty pager view
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=2463b4ea11714543dcb091f83f6dedfa00bae938;p=tig.git

Add notice about empty pager view

Similar to notice for blob view, mention when there is no pager content
to view and suggest the user to open the prompt to run a command.
