/tag command output bugs

[TizzySaurus]

When executing the command /tag without any arguments, a list of all tags is displayed. However, for some reason there's a random bullet point at the top of the list:

Similarly, when the "Did you mean" message comes up for a non-exact multi-match, such as /tag name:f-str, the "Did you mean ..." has a space before the ... that shouldn't be there:

The relevant lines of code appear to be here and here, although I've not delved too deeply into the code so this could be wrong.

It's because of tag groups, #1545, we don't have any tag groups yet, so all tags are under the default group which has no name, hence is just a bullet point. Related: #2423

I would like to work on this issue.

@tarunsamanta2k20 hey, are you stilling working on this ?

These are some of changes we should be doing:

• Change the tag embed footer to remove prefix and use /
  

• We need better help message to tell users on how to use tags from a group. Currently, the syntax to view a tag from a group is /tag name:<group_name> <tag_name>, this has to be mentioned in the tag help message.
  

• We could also change the slash command auto complete to show tags under groups and invoke them by just selecting it from the suggested items. Currently, only tag names outside groups are shown

An update on the points proposed in the issue:

• Empty bullet (fixed typos in tags embed.  #3011)
• "Did you mean ..." (fixed typos in tags embed.  #3011)
• Tag embed footer (Reference the /tag slash-command instead of the old !tags in the footer of tags listings #2987)
• Extra aliases in tag suggestions

@RohanJnr, regarding improving the docs for /tag -- although we don't actually have any tag groups yet, I agree it could perhaps be made clearer. I've opened a separate issue for it since this is unrelated to the /tag output in this issue. (#3014)

Now it looks like the aliases cluttering already have an issue of its own: #2345. So I'll close this issue since everything mentioned has been addressed.
