This function determines whether run-together words will be treated as legal compounds. That is, "thecat" will be a legal compound, although there should be a space between the two words. Changing this setting only affects the results returned by pspell_check(); pspell_suggest() will still return suggestions.

$pspell_config = pspell_config_create("en");
$pspell_link = pspell_new_config($pspell_config);
