keep other autocmds, 'autocmd! -> autocmd'

[robinro]

• fixes #47
• fixes #61
• clearing autocmds is not necessary, double calls are unlikely and won't cause harm

Maybe I'm missing something that needs autocmd!, but in my setup it's not needed and will fix the bug in #47

+1. Should be merged. It allows me to fix (with another additional patch) the issue #61.

@joe-skb7 glad this helps you! What other patch is needed?

[joe-skb7]

@robinro Thanks for your patches! They fixed almost all issues I was suffering from. The last issue I have is described at #61.

Basically I tend to check some quick ideas quite often. To do that I'm creating new main.c file and put some code in it. I don't want to write boilerplate code each time though, so I created ~/.vim/skeleton/template.c file with boilerplate, like that:

#include <stdio.h>
#include <stdlib.h>

int main(void)
{
    return EXIT_SUCCESS;
}

And added next line into my ~/.vimrc:

au BufNewFile main.c silent! 0r ~/.vim/skeleton/template.c

Now when I'm creating new main.c file with vim, like that:

vim main.c

I have template code added to it instantaneously.

But the problem is that this trick doesn't work when file-line plugin is in use. I managed to workaround this issue with your patch plus my hacky change to the plugin. The change is described at #61 as well. I even forked this project and added 2 of your patches and my workaround: https://github.com/joe-skb7/file-line . And my workaround is here: https://github.com/joe-skb7/file-line/commit/6108b56cec1c2c1d75dc0080e6757c2d393016c6

I'm not really good with vim script language, so this hack is only thing I came up with, sorry :( If you could find a proper solution to this issue and write production-ready patch -- I would be really happy, though :)

It would be also great if you can pull your pending changes to your forked file-line project, so everybody can use it instead of this original one (seems like it's dead in the water, probably author abandoned it).

Thanks!

UPDATE

@robinro I see your patches are merged now. Thanks @bogado !

@joe-skb7 sorry for closing #61 too quickly. I'll put #62 on my agenda for next week.

Thanks @bogado for merging.
