Re: [Bug] incorrect indent of next heading after org-paste-subtree

[Samuel Wales <samologist@gmail.com>]

fwiw
[idk if this is useful but here just in case]

iirc, outline mode does not include the final newline for subtrees in
at least one case.

yet, many users and much code assume or ensure that lines are
terminated with a final newline.

this can result in unexpected behavior.  it required code to ensure
compatibility and flexibility, and it required consideration for edge
cases.  sometimes the workarounds would have to be worked around by
the calling code.

core emacs code like sorting assumed/assumes newline.

org would assume or provide none in some [but not all] cases.

user or package code might naturally kill a subtree by killing the
whole line when folded or killing each of the lines.  those include
final newline.  or set require-final-newline.  this is anissue for
things similar to editing source blocks or capture.

the usual bugs were unexpected presence or absence of newlines.  idk
if htat might help you debug or not.
