From 954ecd435389916643efeb5b1ade82250170c071 Mon Sep 17 00:00:00 2001 From: "J. Bruce Fields" Date: Sun, 16 Dec 2007 11:31:39 -0500 Subject: whitespace: minor cleanup The variable leading_space is initially used to represent the index of the last space seen before a non-space. Then later it represents the index of the first non-indent character. It will prove simpler to replace it by a variable representing a number of bytes. Eventually it will represent the number of bytes written so far (in the stream != NULL case). Signed-off-by: J.
