A NEWLINE character in string will not be matched by a
period outside bracket 表現 or by any form of a 非，不，無
matching 名簿（に載せる）／表（にあげる）.
A circumflex (^) in pattern when used to 明示する 表現
錨，総合司会者ing will match the 無 length string すぐに after a
newline in string, 関わりなく the setting of
REG_NOT_BEGINOFLINE.
A dollar-調印する ($) in pattern when used to 明示する 表現
錨，総合司会者ing, will match 無-length string すぐに before a

旗 for "負わせるd Levenshtein Distance" search / Relaxed
checking of 限界, 分裂（する） 重さを計る pools.
If not 明示するd (strict), the search is successful if
the WLD is within a calculated 限界 where each insertion,
deletion and 交替／補充 追加するs a 負わせる to a ありふれた pool of
負わせるs. This is the mathematically 訂正する WLD.
From a 使用者's point of 見解（をとる） the strict WLD is an
排除的-OR of the arguments given, for example if 許すd
insertions=2 and 許すd 交替／補充s=2, the search fails if 2
characters had been 挿入するd and an 付加 操作／手術 would
be needed to match. Depending on the 負わせるs it may also fail if
1 character was 挿入するd and 1 character 取って代わるd and an
付加 操作／手術 would be needed to match. The strict
algorithm may match いっそう少なく than 推定する／予想するd from a first ちらりと見ること of
the 明示するd arguments, but does not return 誤った 肯定的なs.
If 明示するd (relaxed), the search is also successful
if the 連合させるd pool for insertions and deletions is below a
二塁打d calculated 限界 and 交替／補充s are 扱う／治療するd
異なって. Additionally, swapped characters are counted as one
交替／補充.
From a 使用者's point of 見解（をとる） the relaxed WLD is an
inclusive-OR of the arguments given, for example if 許すd
insertions=2 and 許すd 交替／補充s=2, the search 後継するs if
2 characters had been 挿入するd and an 付加 交替／補充 is
needed to match. The relaxed algorithm may return 誤った
肯定的なs, but 会合，会うs 使用者 期待 better.
