Multiple filenames accepted but not linted

[adamchainz]

cfn-lint version: (cfn-lint --version) 0.6.1

Description of issue. The argument parser happily accepts multiple template filenames but only the first is actually checked, which could lead to someone accidentally believing all their templates are good when only the first is.

$ echo null > test1.yml
$ echo null > test2.yml
$ cfn-lint test1.yml test2.yml
E0000 Null value at line 0 column 0
test1.yml:1:1

#149 would add support for multiple filenames but until that is done this is a bit of a bug :)

Yeah, i can see where that would be confusing. We can trap that for now until we have a multi-file solution. As far as that goes, I'd be willing to re-open discussion on it now that core linting functionality has settled down a bit...

#331 is working towards fixing this one.

Should be fixed with v0.7.4. This looking good now @adamchainz ?

Yes thanks!
