      number of sub-patterns, "i"th captured sub-pattern is

+CAVEAT: An optional sub-pattern that does not exist in the matched
+string is assigned the empty string. Therefore, the following will
+return false (because the empty string is not a valid number):
+.sp
+   int number;
+   pcrecpp::RE::FullMatch("abc", "[a-z]+(\e\ed+)?", &number);
+.sp
 The matching interface supports at most 16 arguments per call.
 If you need more, consider using the more general interface
 \fBpcrecpp::RE::DoMatch\fP. See \fBpcrecpp.h\fP for the signature for
 \fBDoMatch\fP.

+.SH "QUOTING METACHARACTERS"
+.rs
+.sp
+You can use the "QuoteMeta" operation to insert backslashes before all
+potentially meaningful characters in a string. The returned string, used as a
+regular expression, will exactly match the original string.
+.sp
+  Example:
+     string quoted = RE::QuoteMeta(unquoted);
+.sp
+Note that it's legal to escape a character even if it has no special meaning in
+a regular expression -- so this function does that. (This also makes it
+identical to the perl function of the same name; see "perldoc -f quotemeta".)
+For example, "1.5-2.0?" becomes "1\e.5\e-2\e.0\e?".
