[PATCHv2 4/4] commit.c: Fix type missmatch warings from msvc

["Sören Krecker" <soekkle@freenet.de>]

Fix compiler warings from msvc in date.c for value truncation from 64
bit to 32 bit integers.

Also switch from int to size_t for all variables with result of strlen()
which cannot become negative.
