Subject: [PATCH] QSpan: fix an MSVC warning-turned-error:

  qspan_p.h(35): error C2220: the following warning is treated as an error
  qspan_p.h(35): warning C4245: 'initializing': conversion from 'int' to 'const size_t', signed/unsigned mismatch

Add an explicit (functional-style) cast to silence it.
