OK, if we don't support bundling flags at all then -x=y and -xy would do
the same thing and pickaxe's -Stext would work too.  But we could not
make option flag parsing global then (-S=value -> search "=value" or
"value"?).

Maybe we should just change -Stext to -S=text or -S text.

Better to support only -x=y or -x y, not both.

Yes

No :)
