From c2e9364a06df55e70d7652d37bb4d712f6b3bb3e Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ren=C3=A9=20Scharfe?= Date: Sat, 7 Mar 2009 14:06:49 +0100 Subject: [PATCH] cleanup: add isascii() Add a standard definition of isascii() and use it to replace an open coded high-bit test in pretty.c. While we're there, write the ESC char as the more commonly used '\033' instead of as 0x1b to enhance its grepability.
