Subject: [PATCH] Make tab-line-switch-cycling work with buffer groups
Date: Mon, 22 Nov 2021 20:16:09 -0800

[Message part 1 (text/plain, inline)]

Currently, `tab-line-switch-cycling' has no effect in the presence of any
tab that isn't associated with a buffer, such as the `group-tab' that
exists when `tab-line-tabs-function' is `tab-line-tabs-buffer-groups'. This
patch modifies `tab-line-switch-to-{next,prev}-tab' to remove any such tab
from consideration.
