pspell_config_runtogether()
should be used on a config before calling
pspell_new_config(). This function determines whether
run-together words will be treated as legal compounds. That
is, "thecat" will be a legal compound, athough 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.
