Errors or omissions in documentation of option files syntax

The manual https://mariadb.com/kb/en/configuring-mariadb-with-option-files/#option-file-syntax
Configuring MariaDB with Option Files – Option File Syntax
has some errors or omissions. I checked with the mariadb client that comes with version 11.4.
1. "The syntax of the MariaDB option files are:"
is itself bad syntax. It should be
"The syntax of the MariaDB option files is:"
2. "Lines starting with # are comments."
is incomplete because such comments can start after the start of a line. It should be
"# is the start of a comment as far as the end of a line.
3. There's nothing about semicolons. Somewhere, probably just after the bit about #, should be
"Lines starting with ; are comments."
4. "Option groups use the syntax [group-name]."
This is vague, it doesn't say where. It should be
"Option groups begin with a line containing a group name inside square brackets: [group-name].
5. "Dashes (-) and underscores (_) in options are interchangeable."
I believe elsewhere in the manual it's slightly more common to call "-" 0x2d a hyphen.
And I believe it would be a bug if user=ad-min is the same as user=ad_min. It should be
"Hyphens (-) and underscores (_) in option names are interchangeable."
See also MDEV-13989.
6. "Double quotes can be used to quote values "
Single quotes can be used too, unless allowing them is an error. It should be
"Double quotes or single quotes can be used to quote values."
By the way, user=admin and user="'admin'" are the same thing though I won't pretend to care.
