From 220be537a03f029e1e619003d6f7def10103a156 Mon Sep 17 00:00:00 2001 From: Denys Vlasenko Date: Sat, 31 Mar 2018 19:21:31 +0200 Subject: ash: use pgetc_eatbnl() in more places Part of upstream commit: Date: Thu Mar 8 08:37:11 2018 +0100 Author: Harald van Dijk parser: use pgetc_eatbnl() in more places dash has a pgetc_eatbnl function in parser.c which skips any backslash-newline combinations. It's not used everywhere it could be. There is also some duplicated backslash-newline handling elsewhere in parser.c. Replace most of the calls to pgetc() with calls to pgetc_eatbnl() and remove the duplicated backslash-newline handling. Signed-off-by: Herbert Xu Not adding "readtoken1(pgetc_eatbnl(), DQSYNTAX..." changes, since readtoken1() handles the "starts with backslash + newline" case itself.
