Nginx -V Output Format

[Nginxuser]

OK, This is not exactly the most critical thing in the scheme of things but it would be nice if some formatting could be applied to the output of the nginx -V command.

What I am thinking of is a new line before every " --" in the configure arguments string.

This will give the far more readable ...

 --param=ssp-buffer-size=4 -m32 -march=i686 -mtune=atom -fasynchronous-unwind-tables'

as compared to the current ...

When the current output is wrapped in the terminal window, it become basically unreadable.

Minor I know but little things make all the difference ... don't they?

[Maxim Dounin]

There is actually a major difference: current format is usable for copy-n-paste to a command line, while suggested one isn't.

Hello!

Both worlds of readability and allowing for copy pasting can be maintained if the newline character is escaped to give:

Just a thought.

Not really, as this e.g. won't work at on Windows, and won't really allow editing after copy-n-paste even with unix shells.
