Subject: Aligned StringIndexOf() implementation with the spec.
X-Git-Tag: 0.8.5~25
X-Git-Url: http://www.kaiwu.me/postgresql/commit/static/gitweb.js?a=commitdiff_plain;h=4bb4c5eaebe29732edd84db44f9aefa666d9081b;p=njs.git

Aligned StringIndexOf() implementation with the spec.

When searchValue is empty the function should return early
when fromIndex <= len is also true.
