+ maint.mk: improve "can not" detection and generalize rule name
+ * 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_undesirable_word_seq_RE_): New overridable variable.
+ (ignore_undesirable_word_sequence_RE_): New overridable variable.
