It now takes a separators argument, which defaults to WHITESPACE if NULL
is passed.

@ -267,7 +267,7 @@ Features:
* maybe add support for specifier expansion in user.conf, specifically DefaultEnvironment=
* code cleanup: retire FOREACH_WORD_QUOTED, port to unquote_first_word() loops instead
* code cleanup: retire FOREACH_WORD_QUOTED, port to extract_first_word() loops instead
* introduce systemd-timesync-wait.service or so to sync on an NTP fix?
@ -303,7 +303,7 @@ Features:
* exponential backoff in timesyncd and resolved when we cannot reach a server
* unquote_many_words() should probably be used by a lot of code that
* extract_many_words() should probably be used by a lot of code that
currently uses FOREACH_WORD and friends. For example, most conf
parsing callbacks should use it.
