Evangelical vicar in want of a portable second-hand font. Would
dispose, for the same, of a portrait, in frame, of the Bishop-elect of
Vermont.

I think you could quite easily reconstruct the formatting of that,
based on its internal structure. Even in poetry, English doesn't
depend on its formatting nearly as much as Python does; and even
there, it's line breaks, not indentation - so we're talking more like
REXX than Python. In fact, it's not uncommon for poetry to be laid out
on a single line with slashes to divide lines:

A boat beneath a sunny sky / Lingering onward dreamily / In an evening
of July / Children three that nestle near, / Eager eye and willing ear
/ Pleased a simple tale to hear...

in the same way that I might write:

call sqlexec "connect to words"; call sqlexec "create table dict (word
varchar(20) not null)"; call sqlexec "insert into dict values
('spam')"; call sqlexec "insert into dict values ('ham')"

To be sure, it looks nicer laid out with line breaks; but it's
possible to replace them with other markers. And indentation still is
completely insignificant. The only case I can think of in English of
indentation mattering is the one you mentioned of first line of
subsequent paragraphs, not by any means a universal convention and
definitely not the primary structure of the entire document.

Making line breaks significant usually throws people. It took my
players a lot of time and hints to figure this out:
