patch 9.1.0449: MS-Windows: Compiler warnings

Problem:  MS-Windows: Compiler warnings
Solution: Resolve size_t to int warnings

closes: #14874

A couple of warnings in ex_docmd.c have been resolved by modifying their
function argument types, followed by some changes in various function
call sites.  This also allowed removal of some casts to cope with
size_t/int conversion.
