I was just poking thru the macros WRT multicursor support.
Looks like _MultiCursorCallFuncName() is to call some function for each cursor?
This is used in gui_goto_line, but not for gui_goto when going to a line.
All cursors are placed on the same line, maintaining their column position.
Kinda nifty, not sure how this would be useful.
gui_goto_col also appears to support multicursor: Seems more useful.
By default, does anything use gui_goto_line()?
