extract_first_word: Refactor EXTRACT_DONT_COALESCE_SEPARATORS handling
Refactor allocation of the result string to the top, since it is
currently done in both branches of the condition.
Remove unreachable code checking for EXTRACT_DONT_COALESCE_SEPARATORS
when state == SEPARATOR (the only place where SEPARATOR is assigned to
state follows a check for EXTRACT_DONT_COALESCE_SEPARATORS that jumps to
the end of the function.)
Tested by running test-util successfully.
