Flux option parsing incorrectly sets option flag

[SamHerts]

Bug:

If parse_yesno is setting to yes, only the very first bit of opt (OPT_COBO) is flipped for every option passed in.

Spindle/src/flux/flux-spindle.c

Lines 362 to 365 in 585dacf

	if (strcasecmp(yesno, "no") == 0 || strcasecmp(yesno, "false") == 0 || strcasecmp(yesno, "0") == 0)
	*opt &= ~flag;
	else if (strcasecmp(yesno, "yes") == 0 || strcasecmp(yesno, "true") == 0 || strcasecmp(yesno, "1") == 0)
	*opt |= 1;

Fix:

 *opt |= flag;
