just: match both yaml and yml

[msanft]

This fixes a little papercut I ran into when working with the .custom directory, where I wondered why my files weren't included. Turned out we only match against .yml while I used .yaml. This makes it so both endings are valid and included.

Wait, doesn't this result in a glob failure if there's either no yml or no yaml?

@burgerdev no, you can test this by:

$ ll *.{yml,yaml}
"*.yml": No such file or directory (os error 2)
"*.yaml": No such file or directory (os error 2)
$ ll *.yml
"*.yml": No such file or directory (os error 2)

That fails for me:

$ touch a.yaml
$ ls *.{yml,yaml}
ls: cannot access '*.yml': No such file or directory
 a.yaml
$ echo $?
2

Oh, i missed the either. Do you have a suggestion on how to glob this instead? *.y{a,}ml? That would probably all result in the same thing?

[burgerdev]

We could set shopt -s nullglob (docs).

Tested this with yml files only, and with both yml and yaml.

Please don't overengineer this. We use .yml by convention.
