"Please make Copy & Cut commands word on the whole current line in case there is no current selection or at least add a configuration option enabling this behaviour."
This patch implements these feature requests and possibly others:
So I went on a crusade to get this working and finally figured it out.
There is a SCI_COPYALLOWLINE command in the text editor control that
already implements the desired behavior. I just needed to expose it and
make it default. Here is the patch for it.
Note that there is no SCI_CUTALLOWLINE in scintilla. I'll send a request for it.
Also, with this change, the Copy menu item should not require a selection to be enabled. So maybe change that option when this patch is applied.
