Error on initializing (with Xdebug)

[MacDada]

I've just installed psalm with composer require --dev vimeo/psalm.

I try to initialize it, but I get the error:

$ ./vendor/vimeo/psalm/bin/psalm --init
The given path "/vagrant/--ansi" does not appear to be a directory

Lets slightly modify the source code of psalm by adding var_dumps:

var_dump('a', $GLOBALS['argv']);
// If XDebug is enabled, restart without it
(new \Composer\XdebugHandler(\Composer\Factory::createOutput()))->check();
var_dump('b', $GLOBALS['argv']);

$ ./vendor/vimeo/psalm/bin/psalm --init
string(1) "a"
array(2) {
  [0] =>
  string(30) "./vendor/vimeo/psalm/bin/psalm"
  [1] =>
  string(6) "--init"
}
string(1) "a"
array(3) {
  [0]=>
  string(30) "./vendor/vimeo/psalm/bin/psalm"
  [1]=>
  string(6) "--init"
  [2]=>
  string(6) "--ansi"
}
string(1) "b"
array(3) {
  [0]=>
  string(30) "./vendor/vimeo/psalm/bin/psalm"
  [1]=>
  string(6) "--init"
  [2]=>
  string(6) "--ansi"
}
The given path "/vagrant/--ansi" does not appear to be a directory

Notice the --ansi parameter being added after XdebugHandler is called, causing the directory to be wrong.

Thanks for the detailed write-up!
