parser: Fix double-backslash nl in old-style command sub
When handling backslashes within an old-style command substitution, we should not call pgetc_eatbnl because that would treat the next backslash character as another escape character if it was then followed by a new-line. This patch fixes it by calling pgetc. Reported-by: Matt Whitlock <dash@mattwhitlock.name> Fixes: 6bbc71d84bea ("parser: use pgetc_eatbnl() in more places") Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
