Post chars are defined in (nth 1 org-emphasis-regexp-components) in emacs org.
When I initially adapted the list of chars for go, I failed to check how it's
actually used (further down in org.el):
(string-match (concat "[" (nth 1 erc) "\n]") (char-to-string (char-after (point))))
Due to the surrounding [] the `\\` in
'("-[:space:]('\"{" "-[:space:].,:!?;'\")}\\[" "[:space:]" "." 1)
is actually a literal backslash, not an escape of the opening bracket I
guess. I'm not in the mood for thinking any harder about this, so let's hope
this is right. yolo.
