Preceding any other character with a backslash is harmless. For example, insource:/yes\.\no/ will search for pages containing the literal string "yes.no" (case-sensitive).

Therefore, if two adjacent cells contain the same digit, the cells next to the digits must contain the other digit (xxx00x → xx1001). Likewise, if two cells contain the same digit with one empty cell in between, this empty cell must contain the other digit, because otherwise three same digit appears (x1x1xx → x101xx). Eliminate the impossible.

PCRE's syntax is much more powerful and flexible than either of the POSIX regular expression flavors (BRE, ERE) [4] and than that of many other regular-expression libraries. While PCRE originally aimed at feature-equivalence with Perl, the two implementations are not fully equivalent.
