65. Implemented an optional replication feature for patterns in pcre2test, to
make it easier to test long repetitive patterns. The tests for 63 above are
converted to use the new feature.

.SS "Generating long repetitive patterns"
.rs
.sp
Some tests use long patterns that are very repetitive. Instead of creating a
very long input line for such a pattern, you can use a special repetition
feature, similar to the one described for subject lines above. If the
\fBexpand\fP modifier is present on a pattern, parts of the pattern that have
the form
.sp
\e[<characters>]{<count>}
.sp
are expanded before the pattern is passed to \fBpcre2_compile()\fP. For
example, \e[AB]{6000} is expanded to "ABAB..." 6000 times. This construction
cannot be nested. An initial "\e[" sequence is recognized only if "]{" followed
by decimal digits and "}" is found later in the pattern. If not, the characters
remain in the pattern unaltered.
.P
If part of an expanded pattern looks like an expansion, but is really part of
the actual pattern, unwanted expansion can be avoided by giving two values in
the quantifier. For example, \e[AB]{6000,6000} is not recognized as an
expansion item.
.P
If the \fBinfo\fP modifier is set on an expanded pattern, the result of the
expansion is included in the information that is output.
