The `/wup` command selects a tab by the prefix of its name only.
The `/win` will do a substring match based on the first tab
going from the current tab which matches the substring. This can
be confusing, especially since `/win` matches on different types
of tab "names" not only on the name which is shown in the info bar
by default.
The `/wup` command exclusively matches based on the prefix of the
tab.name string. This has the advantage that it is consistent,
deterministic and independent of the currently selected tab.
