If this is a feature rather than a bug, I think the man page should be worded differently: in this case the --title parameter should not be referred to as "Initial Title", which is the same wording used in Preferences for a field that (potentially) represents just a prefix or suffix of the whole titlebar.
Is the --title parameter meant to be a fixed and full terminal title? -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe". Trouble? Contact [email protected]
