Can you provide more details as to exactly what you mean by "startup
doc page"? If it's a file, what is its name?

That used to be true for the various -beta versions, and for some of
the earlier -pre versions, but it isn't true in 5.0.0 or later.

GRASS_GUI is a GRASS variable, not an environment variable.

OK; I see why that is happening. It's a side-effect of a shortcut
which is used in the start-up script. You shouldn't rely upon this
continuing to work in future versions. The correct mechanism is to
ensure that the variable is set in your environment before the
"grass5" script is run (e.g. via your shell's "rc" files).
