ash: parser: Fix incorrect eating of backslash newlines
Keeping up with upstream (in our case, 'before patch' code is not buggy). Upstream commit: Date: Fri, 11 May 2018 23:41:25 +0800 parser: Fix incorrect eating of backslash newlines With the introduction of synstack->syntax, a number of references to the syntax variable was missed during the conversion. This causes backslash newlines to be incorrectly removed in single quote context. This patch also combines these calls into a new helper function pgetc_top. Fixes: ab1cecb40478 ("parser: Add syntax stack for recursive...")
