In Ubuntu 14.04, gnome-terminal have a paramter "Select-by-word characters" to configure what characters can be selected as a word. But it has been removed from the UI menu profile.

In newer gnome-terminal source code, I found a new paratmer word-char-exceptions to replace the old one.

word-char-exceptions: summary>List of ASCII punctuation characters that are not to be treated as part of a word when doing word-wise selection.

We configure this paramter by dconf edior which replaced gconf editor.
