No, it did not. You just did not notice the error. A comma is still allowed even though it's not on your list of allowed characters.
The portions highlighted in red represent ranges of characters, not the three characters which appear literally in the regular expression.

Neither of those is correct. msabhi's example is simply less wrong. zing_foru's unintended range expression spans the entirety of the following list. msabhi's attempt spans the highlighted section.
Within a list, the "-" character specifies a range, so that a-z represents all characters between "a" and "z", inclusive. If you want either "-" or "]" itself to be a member of a class, put it at the start of the list (possibly after a "^"), or escape it with a backslash. "-" is also taken literally when it is at the end of the list, just before the closing "]".
