ash: use pgetc_eatbnl() in more places Part of upstream commit: Date: Thu Mar 8 08:37:11 2018 +0100 Author: Harald van Dijk <harald@gigawatt.nl> 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 <herbert@gondor.apana.org.au> Not adding "readtoken1(pgetc_eatbnl(), DQSYNTAX..." changes, since readtoken1() handles the "starts with backslash + newline" case itself.
