I've found that comments have a restriction for minimum comment length. I.e. it's impossible to post too short comments.
Yet in the same time this can be overcome with using formatting. For example, simple Question fail
comment is too short while _Question fail_
is not (added 2 symbols - actual length increased while comment have same content when it is displayed).
Here is a question about @username
in comments and here - about "overcoming" minimum length, but they still aren't focused on formatting issue.
Is it a bug? Should comment length be counted without paying attention to formatting? (since we're able to show them properly, why do not count real, meaningful comment length - note, this has nothing to do with other special characters, like single _
or similar, only formatting)
