Allow to configure filetype

[gowep]

Hello,
I saw that you chaged the commit filetype in 33ccd4a.
Could you make this optional or a config option?
Right now I use gitcommit as a filetype for lots of settings (spellcheck, disable indentline) and configuring/maintaining this for the new filetype would double the work.

I don't think you should have to duplicate your code. Have you tried the below ftplugin?

ftplugin/NeogitCommitMessage.vim

runtime ftplugin/gitcommit.vim

True that would fix a lot of duplication. But then theres still the problem of plugin settings, e.g.
filetype_exclude for indentline.

Thanks for your help, I am using after/ftplugin/NeogitCommitMessage.vim now and that works well for me.
