So don't set it directly but use `helm-locate-case-fold-search'
for this.
The last option must be the one preceding pattern i.e \"-r\" or \"--regex\".
You will be able to pass other options such as \"-b\" or \"l\"
during helm invocation after entering pattern only when multi matching,
not when fuzzy matching.
Note that the \"-b\" option is added automatically by helm when
var `helm-locate-fuzzy-match' is non-nil and switching back from
multimatch to fuzzy matching (this is done automatically when a space
is detected in pattern)."
