@mislav Would --label and --assignee be necessary once we introduce --search though? Because with --search the user can access all the filters relevant to issues right? I was thinking it'd be better if all the search elements are in one place i.e one flag rather than some in --search and one of them in the other. What do you think?

Oh yes --search can be integrated with --web and that's yet to be done.

@g14a Well, unless otherwise stated, I think that different flags on the same command should generally combine well with each other. For example, if I'm already familiar with gh issue list -l bug -a user syntax, and I just want to add a search term to that command, it would be great if gh issue list -l bug -a user --search "foo" just worked without me having to rewrite the whole query as `gh issue list --search "label:bug assignee:user foo".

@mislav That's actually a good idea to not force the user to use a different flag all of a sudden and forget his older familiarity. Okay so you propose we combine the results of multiple flags and present them as one whole result set. Correct me if I'm wrong?

@mislav I've combined the rest of the flags with --search i.e all flags with keep appending to a search query which finally gets executed. I think the IssueList function can be removed as wouldn't be used in gh issue list after this commit. Also we needn't have Milestone by number and Milestone by title as search does all we need.

Search has been combined with --web as well.

I'd like some feedback on this :)

@mislav I've tried to improve the PR with your feedback and wrote new tests separately for --search with respect to the backwards-compatibility that you mentioned. Hope I didn't make things worse.

@mislav I've completed the minor polish pieces. Thanks for the assistance!

Thank you @g14a for all the hard work!
