Do not subtract one in places like below

src/ls.c:               { 0, SQLT_STR, vFileName,     sizeof(vFileName)-1,   0 },
src/lsdir.c:            { 0, SQLT_STR, vDirectory,     sizeof(vDirectory)-1,     0 },
src/lsdir.c:            { 0, SQLT_STR, vDirectoryPath, sizeof(vDirectoryPath)-1, 0 },
src/lsdir.c:            { 0, SQLT_STR, vGrantable1,    sizeof(vGrantable1)-1,    0 },
src/lsdir.c:            { 0, SQLT_STR, vGrantable2,    sizeof(vGrantable2)-1,    0 },
