Subject: [PATCH] - Handle args in the form /pathto/file[:line[:column]][:] so
 you can double-click on a gcc error in the terminal, type open and
 right-click to edit at the buggy line. Discard last : form gcc errors to
 avoid having to type backspace. Works with Pe for the line at least, BeIDE
 doesn't seem to handle it though the documentations says it should. Others
 apps welcome to handle the be:line and be:column int32s on B_REFS_RECEIVED :)
 - Updated copyright.
