When we moved to using ~/.perfconfig to set the value of use_browser,
it changed from a boolean to an int so that the convention used for
use_pager was followed.
That convention is:
-1: unspecified, that is what use_{browser,pager} is initialized
0: Don't use the browser (should be TUI), because was explicitely
set to 0/off/false on ~/.perfconfig [tui] cmd =, or because
we're redirecting the stdout to a file or piping it to some
other command (!isatty()).
1: Use the TUI
Some code was not properly audited and continued testing it as a
boolean, this seems to be the last one.
