ash: use pgetc_eatbnl() in more places, take 3
Adding previously skipped "readtoken1(pgetc_eatbnl(), syntax_type..." change from upstream commit: Date: Thu Mar 8 08:37:11 2018 +0100 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. Testcase: PS1='\ :::' should result in ::: prompt, not <newline>::: prompt Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
