There is an established convention for usernames, which is to put "user:" at the start of the line. It can't be the first line of the file but is otherwise not order dependent. The browser plugins and android app implement this and do autofill based on it. That is suggested on the main site.

If you blat your password with generate, it can be recovered because it is in git. A nice to have for pass might be a flag to autoinsert only on the first line, but in lieu of that, pwgen should do the job and is what pass uses under the hood.
