qstring: Move qstring_from_substr()'s @end one to the right

Browse source 
qstring_from_substr() takes the index of the substring's first and
last character.  qstring_from_substr(s, 0, SIZE_MAX) denotes an empty
substring.  Awkward.

Shift the end index one to the right.  This simplifies both
qstring_from_substr() and its callers.
