A ‘\def\::temp{...}\HLet\end=\:temp’ is no good in cases like

because the ‘\end’ is within picture which brings the false part in ‘\ifx \EndPicture\:UnDef \n:end:\else \o:end:\fi’.

The \csname before:begin#1\endcsname sends \csname after:end#1\endcsname to the end with \csname after:end\endcsname. Hence, allowing to change or interrupt the delivery by redefining \csname after:end\endcsname on the way.

The \thebibliography contains a ‘chapter*’ which is a problem here in case of cutoff because we get ‘\SaveEverypar....\HPage...\RecallEverypar....\EndHPage’, where the hypertext also saves and recalls the status. Hence, a partial overlap that would have forced a warning.

The \RecallEverypar must appear first because it sets the counter \n:list, the appropriate \ht:everypar contents, and \ShowIndent or \IgnoreIndent.

The \@doendpe deals with piles of \ends. The ‘\Protect\HtmlPar’ goes to the first paragraph outside the pile.

The \hfill\break is to help prevent losses of space separators.

We might get here leading empty paragrphs after an ‘\end’. Is there a way to remove them without a post processor.

We can’t add grouping of the form ‘\append:defI\begin{\bgroup}.......\pend:defI\end{\egroup}’ for catching enclosed fonts because \begin{...} commands might include parametric subcommands like in ‘\begin{list}{default-label}{definitions}...\end{list}’.

LaTEX changes the meaning of ‘\ht:everypar’ upon reaching ‘\end’. Hence, the ‘\ht:everypar{}\begin{...}...\end{...}’ does not let the effect of ‘\ht:everypar’ through.
