Cannot parse router comment "/ [get]"

[lc-jordanfelix]

Describe the bug
Since upgrading to v1.6.4 from v1.6.3, some of our routes no longer parse. The problem routes are annotated like this

// @Router / [get]

We have an annotated base path for the set of routes. The problem routes are "/" off the base path.

To Reproduce
Steps to reproduce the behavior:

1. Annotate a function with

// @Router / [get]

2. run swaggo
3. See error

Expected behavior
Route parses and generates as usual

This issue seems to be a result of a PR #552 on 10 Nov,2019

We download the latest version for every deployment and we only just started having this issue yesterday, with no changes to the swaggo annotations.
