That wouldn't be much cleaner, actually, because there would have to
be an option to select or de-select this behaviour because we don't
always want it -- at least I know that I wrote some functions where I
intentionally didn't use `-', in cases where the lower level functions
just knew better what to produce as descriptions.
So that is one case where just counting lines gives wrong results. Two
other cases are: functions that are not intended to be used as helper
functions (and those are responsible for many of the uses of _wanted)
and cases where the `-' might be on a second line. I don't know how
many cases fall into the second category, but a bit of grep and wc
shows 131 cases where the line with _wanted ends in a backslash.
But of course, anyone is free to hack on the completion code -- always
was. The best place would probably be _all_labels, the place where we
now do the search for `-'. And make sure to check the uses of _wanted
so that we don't use stuff we want to have.
