Subject: Removed hardcoded pager progress indicator and add %P format code to $pager_status... 
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=79985c786a0c3968af6510f1e4b9b3bace87fbcc;p=neomutt

Removed hardcoded pager progress indicator and add %P format code to $pager_status which contains the same information.

Append "%> -- (%P)" to $pager_status to emulate old behavior.

Closes #2087.
