While you can remove the arguments, it is not recommended. Notepad++ would work but there are a few things may annoy you.

See the manual for more information.

• multiInst is used so that notepad++ starts in a new window if it is already started. Without that argument, it would open a new tab and you will need to close notepad++ in order to make the commit.
• notabbar just removes the tab bar as you don’t need it.
• nosession does not open previously opened files in notepad++ when editing the commit message.
• noplugin starts notepad++ without plugins. This makes it faster to start.
