[gtksourceview/meson.msvc: 2/5] gtksourceutils.c: Don't define variables in a for loop statement

    gtksourceutils.c: Don't define variables in a for loop statement
    
    pre-C99 compilers don't like this idea...
    
    Also change a call of snprintf() to g_snprintf() so that all supported
    platforms can build the code properly.
