[AUCTeX] auctex buttons in emacs tool-bar

[Sureyya Sahin]

Hi,

I am trying to use the emacs tool-bar on the left as opposed to top
(default); however, when I choose this, I end up having the auctex
toolbar separator to remain vertical instead of transforming to
horizontal when the tool-bar of emacs is on the left side (or right
side). In this configuration, the separator occupies too much of space
and I am not happy with this.

My question is whether to file a bug or whether there is a workaround.
Any help or suggestion would be appreciated.
