Otherwise fall back to the computed argv[0].

Many thanks to Stanislav Motylkov for having investigated this bug!
fixes CORE-12931 and all its duplicates: CORE-13892 CORE-13898 CORE-14066
Fix picked from 0.4.10-dev-201-g f215f394d8
observed with MSVC2010SP1 16.0.40219.1 x86-target in dbg+rls-config several times:
sdk\lib\crt\string\wtoi64.c(28) : warning C4146: unary minus operator applied to unsigned type, result still unsigned
sdk\lib\crt\string\wtoi64.c(194) : warning C4146: unary minus operator applied to unsigned type, result still unsigned
the fix is a PARTIAL port of 0.4.15-dev-2951-g 5d8e834897
and while touching the file
fix another white-space-glitch.
in sum that brings us 100% in sync in this file to master 0.4.15-dev-3264-g570cedf.
The cFileName member of WIN32_FIND_DATA is an array of MAX_PATH(260). Using strcpy/wcscpy with the target buffer being smaller is potentially bad. Corresponds to CID 1401198 and 1401195.
