One interesting bit in the config is:

'extra_config' => {
...
'HEAD' => [
'update_process_title = off'
],
'REL_13_STABLE' => [
'update_process_title = off'
]

I wonder what where the output of "starting debugger for pid 53762" ends up? I
assume it's triggered by
'CYGWIN' => 'server error_start=c:\\ncygwin64\\bin\\dumper.exe -d %1 %2',

https://cygwin.org/cygwin-ug-net/using-cygwinenv.html
says "The filename of the executing program and it's Windows process id are appended to the command as arguments. "

but nothing about %1 and %2 :(. I those are just "executing program" and
"Windows process id" respectively?
