+
+ maint.mk: prohibit doubled words
+ Detect them also when they're separated by a newline.
+ There are 3 ways to customize it:
+ - disable the test on a per file basis, as usual with rules using
+ $(VC_LIST_EXCEPT)
+ - replace the default doubled-word-selecting regexp (affects all files)
+ - ignore a particular file-vs-doubled-word match
+ I nearly used that last one to ignore the "is is" match in
+ coreutils' NEWS file, since the text was "ls -is is ..."
+ To do that, I would have added this line to cfg.mk:
+ ignore_doubled_word_match_RE_ = ^NEWS:[0-9]+:is[ ]is$
+ but it would have ignored any "is is" match in NEWS.
+ Low probability, but still...
+ Instead, I changed the text, slightly:
+ - ls -is is now consistent with ls -lis in ignoring values returned
+ + "ls -is" is now consistent with ls -lis in ignoring values returned
+ * top/maint.mk (prohibit_double_word_RE_): Provide default.
+ (prohibit_doubled_word_): Define.
+ (sc_prohibit_doubled_word): New rule.
+ (sc_prohibit_the_the): Remove. Subsumed by the above.
