Subject: [PATCH] browser: make the keystrokes ^W^Y and ^W^V work again

The functions to_first_file() and to_last_file() can get called from
do_statusbar_input(), which is called indirectly from do_prompt(),
and are expected to make the corresponding adjustment.

This fixes https://savannah.gnu.org/bugs/?61273.

Bug existed since version 5.0, commit 07c1ac90.
