Escaping #+ lines is optional and mostly necessary to avoid confusing
parser.
For example, one would need to escape


#+CATEGORY: foo
#+begin_src text
,#+end_src
#+end_src

for obvious reasons.

I have clarified the syntax document in
https://git.sr.ht/~bzg/worg/commit/b1d16efc

Hope the new examples explain better what is going on.

Unlike #+ lines, * is _always_ interpreted as a heading. So, it must
always be escaped.

The parser simply removes commas in all the ,* and ,#+ lines.

However, the following test document parses as a lesser block despite 
containing a line starting with an unescaped #+:
```
#+CATEGORY: foo
#+begin_src text
#+CATEGORY: bar
#+end_src
```


You have to quote #+end_src inside source code blocks or #+end_example 
in the case of #+begin_example block


#+begin_example
,#+end_example
#+end_example

Lesser blocks allowing unescaped lines

This happens in worg at:

However, the following test document parses as a lesser block despite 
containing a line starting with an unescaped #+:
```
#+CATEGORY: foo
#+begin_src text
#+CATEGORY: bar
#+end_src
```

which parses as:
```
(org-data
(:standard-properties
  [1 1 1 60 60 0 nil org-data nil nil nil 3 60 nil # nil nil 
nil]
  :path nil :CATEGORY "foo")
(section
  (:standard-properties
   [1 1 1 60 60 0 nil first-section nil nil nil 1 60 nil # 
nil nil #0])
  (keyword
   (:standard-properties
[1 1 nil nil 17 0 nil top-comment nil nil nil nil nil nil # nil nil #1]
:key "CATEGORY" :value "foo"))
  (src-block
   (:standard-properties
[17 17 nil nil 60 0 nil nil nil nil nil nil nil nil # nil 
nil #1]
:language "text" :switches nil :parameters nil :number-lines nil 
:preserve-indent nil :retain-labels t :use-labels t :label-fmt nil :value 
"#+CATEGORY: bar\n"
```

whereas I would expect this to be
```
(section
  (keyword :key "CATEGORY" :value "foo")
  (paragraph "#+begin_src text")
  (keyword :key "CATEGORY" :value "bar")
  (paragraph "#+end_src")
)
```

This test document shows that lines with an unescaped "*" do break up the 
lesser block:
```
* foo
#+begin_src text
* bar
#+end_src
```
