ash: use pgetc_eatbnl() in more places, take 2
Adding previously skipped "readtoken1(pgetc_eatbnl(), DQSYNTAX..." changes
from 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.
