Patch implement asymmetric mail from Justin Rebelo (hermit) saying:
"It still needs one more thing which I was unable to do. When you group together enough tabs to fill up the window title, it doesn't start shrinking the tabs.
...
but this is a start maybe for you to clean up and then get the support into pekwm svn."""
The patch has been applied and work on handling growin/shrinking of tabs when required has been started even though it is not yet working.
