Subject: [PATCH 1/2] Split table cells on a pipe that follows a closing code
 span backtick

_split_row did not split on any pipe preceded by a backtick, to keep
`|` inside a cell (#399). That also covered a pipe right after the
backtick that closes a code span, so a compact row like
|`-v`|verbose| put "verbose" into the first cell. Only keep the pipe
when the backtick before it opens a code span.
