While 'git checkout <submodule>' should not update the submodule's
working directory, it should update the index.  This is in line with
how submodules are handled in the rest of Git.

While at it, test 'git reset [<commit>] <submodule>', too.

Some old versions of gcc don't seem to like us negating an
enum constant. Let's work around it by negating the other
half of the comparison instead.

Commit 0925ce4d(Add map_user() and clear_mailmap() to mailmap) broke the
lower-casing of email addresses.  This mostly did not matter if your
.mailmap has only lower-case email addresses;  However, we did not
require .mailmap to contain lowercase-only email addresses.

To find the blob object name given a tree and pathname, we were
incorrectly calling "git ls-tree" with a "--" argument followed
by the pathname of the file we wanted to get.

  git ls-tree <TREE> -- --dashed/path/name.c

Unlike many command-line interfaces, the "--" alone does not
symbolize the end of non-option arguments on the command-line.

ls-tree interprets the "--" as a prefix to match against, thus
the entire contents of the --dashed/* hierarchy would be
returned because the "--" matches "--dashed" and every path
under it.

Thanks to Anton Gyllenberg for pointing me toward the
Twisted repository as a real-world example of this case.

Embarrassingly, the common prefix calculation did not work properly, due
to a mistake in the assignment: instead of assigning the dirname of the
current file name, the dirname of the current common prefix needs to
be assigned to common prefix, when the current prefix does not match the
current file name.

On a 32-bit system, the maximum possible size for an object is less than
4GB, while 64-bit systems may cope with larger objects.  Due to this
limitation, variables holding object sizes are using an unsigned long
type (32 bits on 32-bit systems, or 64 bits on 64-bit systems).

When large objects are encountered, and/or people play with large delta
depth values, it is possible for the maximum allowed delta size
computation to overflow, especially on a 32-bit system.  When this
occurs, surviving result bits may represent a value much smaller than
what it is supposed to be, or even zero.  This prevents some objects
from being deltified although they do get deltified when a smaller depth
limit is used.  Fix this by always performing a 64-bit multiplication.

When --pickaxe-regex is used, forward past the end of matches instead of
advancing to the byte after their start.  This way matches count only
once, even if the regular expression matches their tail -- like in the
fixed-string fork of the code.

E.g.: /.*/ used to count the number of bytes instead of the number of
lines.  /aa/ resulted in a count of two in "aaa" instead of one.

Also document the fact that regexec() needs a NUL-terminated string as
its second argument by adding an assert().
