From c2694952e33764818983fa247dcee72113c6ac6a Mon Sep 17 00:00:00 2001 From: Matthew DeVore Date: Thu, 27 Jun 2019 15:54:11 -0700 Subject: strbuf: give URL-encoding API a char predicate fn Allow callers to specify exactly what characters need to be URL-encoded and which do not. This new API will be taken advantage of in a patch later in this set.
