PATCH: Update the description of S flag in the completion

[Sebastian Gniazdowski <sgniazdowski@xxxxxxxxx>]

Hi,
the current description is:
S  -- search substrings in #, %, / expressions

which:
- is counter the manual and usage-proof, as the flag affects / and //
substitutions only in the non-greedy way.

The patch changes the description to:
S -- match non-greedy in /, // or search substrings in % and # expressions

(the referenced manual fragment is:
       S      Search substrings as well as beginnings or  ends;  with
#  start  from  the
              beginning and with  % start from the end of the string.
With substitution
              via ${.../...} or ${...//...}, specifies non-greedy
matching, i.e. that  the
              shortest instead of the longest match should be replaced.)
