more robust version of blogpost vim script

this should work with the edge cases. my old one would get choked up processing h2s and make would poop its pants and i'd have to manally rerun my automation. hopefull this fixes it. also i hadded some debugging checks that go off when i send to give a lil info incase it doesn't go through just to help me see whats goin' on better.

looks like the regex is screwing up the codeblock unfortunately

function! Blogpost()
    " Get the current buffer content
