Don't mess with the lock file when inhibit_modification_hooks is set,
just like we do in prepare_to_modify_buffer_1.

* src/buffer.c (Fset_buffer_modified_p)
(Frestore_buffer_modified_p): Doc fixes.
* src/insdel.c (syms_of_insdel) <inhibit-modification-hooks>:
Document in the doc string that this variable also inhibits file
locks and active region handling.  (Bug#29846)

Copyright-paperwork-exempt: yes

with 2 spaces is not broken between 2 lines.

cross-reference to the Org manual.  Make the cross-reference to

a forgotten remnant from time immemoriam).
(Paragraphs): Add a note that 'paragraph-start' and
'paragraph-separate' should not be anchored.

a list.  Return the latest one which has a binding.

Do this by removing a broken optimization in the state cache which put
category text properties on a character between the end of the CPP construct

character.
