[Feature Request] support filter stderr message

[hiberabyss]

When run sql query, there will be following error message in the output:

mysql: [Warning] Using a password on the command line interface can be insecure.

Is it possible to have option to filter such stderr message?

'errorformat' can do that.

The errorformat should only work on quickfix like window? What I want is to get rid of the stderrr message in dbout.

There's no built-in support for this. I supposed you could use a wrapper script, with something like mysql "$@" 2>&1|grep -v '^mysql: \[Warning' or whatever to filter it yourself.
