Hi Juri,

I did not *want* to switch to the current tab as in deliberately
calling tab-bar-select-tab-by-name with the intention to switch
to the current tab.  My test case was with one or two tabs and
the list of tabs was very short, shorter than expected.

I see.  It makes sense to shorten the list of targets to the
minimum.  To me it seems more natural to have a full list.  But I
agree that there is no loss in functionality if the current tab
is not member of the list.

Ciao; Gregor
