Vintage "a" behavior at beginning of empty line

David Niergarth 6 years ago 0
With Vintage active, typing "a" in command mode at the beginning of an empty line causes the cursor to advance to the next line when it should stay on the same line.

The relevant key binding in Vintage/Default.sublime-keymap seems to be
{ "keys": ["a"], "command": "enter_insert_mode", "args":      {"insert_command": "move", "insert_args": {"by": "characters", "forward": true} },      "context": [{"key": "setting.command_mode"}]   },
Any suggestions on how to go about modifying this behavior so "a" never advances to the next line?
