Yes, it's a minor issue. I like minor issues :-)
There are two display problems here:
- a face defined before a heading enters the heading (like the =eee…=)
- a face defined in a heading goes on past the heading (like the *iii…)
I did some tests with org-emph-re (original value: [1]); the interesting part
is \\(?:\n.*?\\)\\{0,1\\} because it is the one that allows the face to extend
up to 1 line below.
The .*? from there comes from the so-called body in
org-emphasis-regexp-components, body="."
I have done some tests and I think that body="\\(?:\\*+[^\n ]\\|[^\n*]\\)."
fixes the first problem. The expression represents a non-heading line: anything
not starting by * (except when the initial * precedes a word) and then many
other characters (a "*?" at the end will be added by org-set-emph-re)
Final value: [2]
Is this added complexity worth it? The bug is unpleasant (headings aren't
coloured as headings) and performance shouldn't be much affected in the common
case because ^\\* fails early. Only visually it is a complex regexp.
I don't know how to detect the other problem inside a regular expression.
Maybe there's some way to ask „don't cross boundaries between headings and
content“.
