* [BUG] 'nolog' and 'debug' options cause "$-" to wreak havoc

Bug: if either the 'nolog' or the 'debug' option is set, trying to
expand "$-" silently aborts parsing of an entire argument.

$ dash -o nolog -c 'set -fuC; echo "|$- are the options|"; \
	set +o nolog; echo "|$- are the options|"'
|
|uCf are the options|
$ dash -o debug -c 'set -fuC; echo "|$- are the options|"; \
	set +o debug; echo "|$- are the options|"'
|
|uCf are the options|

Also, though the 'nolog' option is POSIX[*] and (apart from this bug)
acts like POSIX, it's not documented the dash man page.
