There are several types of options, Unix, bsd, and long.  See the man page for 
ps or man 3 getopt.  IN this case, these are unix options that start with a 
dash.  The space after a unix option is optional.  For bsd options it is 
mandatory and for long options an '=' is required.

Which version?  It may not matter because the most recent version is about 18 
months old.

Maintaining sane/xsane in BLFS may just be more effort than it's worth.
