Skip bidi markers in the pager and index. (closes #3827)
Curses and slang don't support them, so there's little point in
showing them or attempting to somehow deal with them.
This patch adds filtering in the pager, and changes the filtering
added in 6e0aca94cdb0 for the index to completely skip the marker.
