Does hdmi_cvt need the '=' in config.txt?

Question

I've got an HDMI touchscreen for my Raspberry Pi, and the instructions say to add the following to the end of the config.txt file:

max_usb_current=1
hdmi_group=2
hdmi_mode=1
hdmi_mode=87
hdmi_cvt 1024 600 60 6 0 0 0

hdmi_cvt=<width> <height> <framerate> <aspect> <margins> <interlace> <rb>

I've found examples of both on the Internet and on this site.

Which is correct?

@Dirk, because I can't get the screen working (it works fine plugged into a laptop, and it works fine with hdmi_safe=1), and I'm trying to work out whether the instructions are wrong, or if I'm doing something else wrong. — Roger Lipscombe, Commented Nov 27, 2018 at 17:29
because I can't get the screen working well, logic tells me that it only takes 2 boots. If both don't work then the rest of the line has an error and it's irrelevant if you need the equal sign or not. — Dirk, Commented Nov 27, 2018 at 18:34
So you have an answer below: both work. Time to solve the real problem :) — Dirk, Commented Nov 27, 2018 at 18:35

I've just tested this on my Pi3 with 5 inch touchscreen - both work - with and without the '='.

hdmi_group=2
hdmi_mode=87
hdmi_cvt=800 480 60 6 0 0 0

Worked

hdmi_group=2
hdmi_mode=87
hdmi_cvt 800 480 60 6 0 0 0

Worked
