Bug #57093 --install option to mysqld not working if not listed first

Description:
C:\mysql556rc\bin>mysqld --defaults-file=c:\mysql556rc\my.ini --install mysql556rc

C:\mysql556rc\bin>net start mysql556rc
The service name is invalid.

error log:
100929 19:53:27 [ERROR] mysqld: unknown option '--install'

C:\mysql556rc\bin>mysqld --install mysql556rc --defaults-file=c:\mysql556rc\my.ini
Service successfully installed.

C:\mysql556rc\bin>net start mysql556rc
The mysql556rc service is starting..
The mysql556rc service was started successfully.

How to repeat:
As per the above

Yet, contradictory, if --install is not used, --defaults-file needs to be the first option:

C:\mysql\bin>mysqld --server-id=5 --defaults-file=c:\mysql\my.ini
<terminates>

Error log:
100929 20:05:31 [ERROR] mysqld: unknown variable 'defaults-file=c:\mysql\my.ini'
100929 20:05:31 [ERROR] Aborting

(Notice the missing dashes also)

Very confusing, especially when the manual says "To work properly, each of these options [including --defaults-file] must immediately follow the command name" - yet clearly --install needs to go before it and not behind.

(http://dev.mysql.com/doc/refman/5.1/en/option-files.html)

Looks like it's a documented:
http://dev.mysql.com/doc/refman/5.5/en/windows-start-service.html

In that case, please update manual at:
http://dev.mysql.com/doc/refman/5.1/en/option-files.html

To include this exception (--install)

After the docs have been updated, please assign back to me. I'd like to make a FR out of this to have the behavior changed to accept options in any location.

Documentation updated. Assigning back to Roel per Roel's request.

Feature request (preferably for 5.5): please change the behavior to accept (any) options in any location.
