Filename-format rule: fix filename extension regex: ".go" to "\\.go".

[denarced]

Just a quick fix for an obvious issue with the filename regex. Filename extension's dot wasn't escaped so, for example, "awesome$go" was considered a valid filename.

Good catch, but a file naned awesome$go, won't be a go files, so something that revive would catch, no?

I mean the regex wasn't perfect, and you are fixing it. Thank you about that.

But it was a crime without victim, right ?

[denarced]

True, very hard to find a victim. I've seen this type of slip-ups (not escaping filename extension dots in regex) many times before and in all cases, no one ever found the defect in production. I don't know the project so there was a chance that the fix was somehow useful, it was suppose to be quick (it actually wasn't), so I just fixed it. If I ended up breaking something, please just revert the commit :).

I'll let other people provide feedbacks.

But for me, you "bug fix" is legitimate

Hi @denarced, thanks for the fix.
