| .SH DESCRIPTION |
| .rs |
| .sp |
| This sets a maximum length for the number of characters matched by a |
| variable-length lookbehind assertion. The default is set when PCRE2 is built, |
| with the ultimate default being 255, the same as Perl. Lookbehind assertions |
| without a bounding length are not supported. The result is always zero. |
