36 when the user extends selections (double-click). Right now, it tries
37 to select urls and complete shell-quoted arguments, which is very
38 convenient, too, if your ls supports "--quoting-style=shell".

71 The first argument passed to them is an object private to each terminal
72 and extension package. You can call all "urxvt::term" methods on it, but
73 its not a real "urxvt::term" object. Instead, the real "urxvt::term"
74 object that is shared between all packages is stored in the "term"
75 member.

116 double click) and is either supposed to return false (normal
117 operation), or should extend the selection itelf and return true to

151 state information is up-to-date when this happens. For
152 interoperability, the string should start with the extension name
153 and a colon, to distinguish it from commands for other extensions,
154 and this might be enforced in the future.
