TopBar strings not truncated correctly by auto-width (to master)

[linknetx]

For non-concatenated topbar strings each part of the string is truncated seperately by auto-width resulting in incorrect truncation. Also auto-width not working unless the width is specified.

Solution - create vars to concatenate topbar strings prior to auto-width truncation and specify width value for auto-width.

This fixes the problem so is it possible to merge it ?
