Dear Maintainer,

I'm not sure I've marked this bug report correctly; it was not clear
what values I should pick for "borderline unusable, but for only a
small fraction of all users".  Please reclassify as appropriate.

gdb borders on unusable when using a terminal type that does not
support X3.64 escape/control sequences, even though $TERM is set
correctly and gdb thus should know this is the case.  For example,
here's what I see, cut-and-pasted directly from the terminal window I
ran gdb in:

Telling gdb "!printenv TERM" prints "mterm4l"; the actual $TERM setting
is "mterm" - I conjecture that gdb is postprocessing the output of the
command, adding yet more inappropriate X3.64 sequences.

If there is a way to turn this off, it is far too well hidden; I have
found commands for changing the colours (er, sorry, "colors") used to
decorate various pieces of the UI, but nothing at all for completely
turning it all off.  Nor should I need to, when I've already told gdb,
via $TERM, that X3.64 sequences will not work.

Control: severity -1 wishlist

So, GDB 16.2 (from unstable) supports NO_COLOR (https://no-color.org/),
so that should be an easy way to disable colours on it.

GDB from bookworm and unstable both support "set style enabled off",
which does what you want.

I understand that the request here is that GDB should be aware of TERM
and set things accordingly, but I don't consider that to be an important
bug, so I'm adjusting the severity to wishlist.  Meanwhile, if that's
still something important for you, could you:

1) Verify that GDB from unstable/bookworm still suffers from this
problem.

2) File an upstream issue if that's still the case.

Thanks,
