mysql cli doesn't accept -p option in command line

[Mats Luspa]

I'm running Ubuntu Bionic 18.04.6 LTS and the mysql version is "mysql Ver 14.14 Distrib 5.7.42, for Linux (i686) using EditLine wrapper".
The bug is that -p option doesn't work but --password option works in command line. For example:

This doesn't work:
mysql -u <username> -p <password> < sql.txt
But this work:
mysql -u <username> --password=<password> < sql.txt

/Regards Mats

It seems that you now must not have a space between -p and password, like -p<password>. But it has worked with space so this must have been changed.
