ChangeLog, mke2fs.c, tune2fs.8.in:
tune2fs.8.in: Fix minor display bug in the nroff.
mke2fs.c (show_stats, write_inode_tables): Use the log10 function to
calculate the display of block numbers so that things look nice on an
80 character display.
mke2fs.c (usage): Add the sparse-super-flag to the usage message.
ChangeLog, e2fsck.c, pass1.c, pass2.c, problem.c, problem.h, unix.c:
unix.c (main): Move ext2fs_close() after e2fsck_free_context() since
e2fsck_free_context may reference data in ctx->fs.
e2fsck.c (e2fsck_reset_context): Make sure ctx->fs is non-NULL before
checking ctx->fs->dblist.
pass1.c (e2fsck_pass1): Use the device check subroutine on FIFO's and
Socket's, so that we catch bogus immutable inodes.
pass2.c (process_bad_inode): Process bad socket and fifo's.
problem.h, problem.c: Define new problem codes PR_2_BAD_FIFO and
PR_2_BAD_SOCKET.

ChangeLog, debugfs.8.in, debugfs.c:
Add a -V option which displays the current version.
ChangeLog, unix.c:
unix.c (e2fsck_update_progress): Remove unused variables.
ChangeLog, inode.c:
inode.c (get_next_blockgroup): Fix bug where if get_next_blockgroup()
is called early because of a missing inode table in a block group, the
current_inode counter wasn't incremented correctly.
ChangeLog, tst_uuid.c:
tst_uuid.c (main): Fixed bogus declaration of the main's argv parameter.
ChangeLog, test_icount.c:
test_icount.c (main): Fix main() declaration so that it returns int,
not void.
Many files:
fsck.c (ignore): Remove unused variable cp.
chattr.c (fatal_error):
tune2fs.c (usage):
lsattr.c (usage):
dumpe2fs.c (usage):
badblocks.c (usage): Remove volatile from declaration.
fsck.c: Change use of strdup to be string_copy, since we don't trust
what glibc is doing with strdup. (Whatever it is, it isn't pretty.)
