maint.mk: adjust previous commit

Change "misc" in names to "undesirable_word_seq".
"misc" is rarely desirable, in a name ;-)
Define and use ignore_undesirable_word_sequence_RE_ properly.

        maint.mk: improve "can not" detection and generalize rule name
-       * top/maint.mk (sc_prohibit_misc): Renamed from sc_prohibit_can_not,
-       since we'll probably add a few more word pairs here.
+       * top/maint.mk (sc_prohibit_undesirable_word_seq): Renamed from
+       sc_prohibit_can_not, since we'll probably add a few more word pairs here.
        Use the same technique as in sc_prohibit_doubled_word, so that
        we recognize "can not" also when the words are separated by a newline.
        Suggested by Eric Blake.
        (perl_filename_lineno_text_): Define.  Factored out of...
        (prohibit_doubled_word_): ...here.  Use the new definition.
-       (prohibit_misc_): New var.  Use it here, too.
-       (prohibit_misc_RE_): New overridable variable.
+       (prohibit_undesirable_word_seq_): New var.  Use it here, too.
+       (prohibit_undesirable_word_seq_RE_): New overridable variable.
+       (ignore_undesirable_word_sequence_RE_): New overridable variable.
