Have peek command honor "tagfocus"

The peek command allows looking at details of a function, and it
avoids any trimming to provide full details. However, when using
tagfocus it is useful to still limit to the filtered samples.
With this change peek will honor tagfocus, but it will avoid any
other trimming.
