Bug #40963 mysql-proxy --help output is hard to read

Description:
The proxy help is way wider than a default terminal.  It should be formatted to fit.  There is a huge amount of whitespace between the options and description, which makes it too wide, and also makes it hard to see which thing goes which which.

How to repeat:
Run mysql-proxy --help.

Thank you for a problem report. Verified just as described with 0.7.0:

Usage:
  mysql-proxy.exe [OPTION...] - MySQL App Shell

The problem is that glib2 does not offer a shorter version.
We would either need to reimplement some of the logic to provide a more concise help page, or extend glib2 and submit it upstream.
