  attr: fix leak in free_attr_elem
  t2203: fix wrong commit command

This function frees the individual "struct match_attr"s we
have allocated, but forgot to free the array holding their
pointers, leading to a minor memory leak (but it can add up
after checking attributes for paths in many directories).

In prepare_attr_stack, we pop the old elements of the stack
(which were left from a previous lookup and may or may not
be useful to us). Our loop to do so checks that we never
reach the top of the stack. However, the code immediately
afterwards will segfault if we did actually reach the top of
the stack.

Fortunately, this is not an actual bug, since we will never
pop all of the stack elements (we will always keep the root
gitattributes, as well as the builtin ones). So the extra
check in the loop condition simply clutters the code and
makes the intent less clear. Let's get rid of it.

When we prepare the attribute stack for a lookup on a path,
we start with the cached stack from the previous lookup
(because it is common to do several lookups in the same
directory hierarchy). So the first thing we must do in
preparing the stack is to pop any entries that point to
directories we are no longer interested in.

For example, if our stack contains gitattributes for:

  foo/bar/baz
  foo/bar
  foo

but we want to do a lookup in "foo/bar/bleep", then we want
to pop the top element, but retain the others.

To do this we walk down the stack from the top, popping
elements that do not match our lookup directory. However,
the test do this simply checked strncmp, meaning we would
mistake "foo/bar/baz" as a leading directory of
"foo/bar/baz_plus". We must also check that the character
after our match is '/', meaning we matched the whole path
component.

There are two special cases to consider:

  1. The top of our attr stack has the empty path. So we
     must not check for '/', but rather special-case the
     empty path, which always matches.

  2. Typically when matching paths in this way, you would
     also need to check for a full string match (i.e., the
     character after is '\0'). We don't need to do so in
     this case, though, because our path string is actually
     just the directory component of the path to a file
     (i.e., we know that it terminates with "/", because the
     filename comes after that).

  Documentation: rerere.enabled is the primary way to configure rerere

The wording seems to suggest that creating the directory is needed and the
setting of rerere.enabled is only for disabling the feature by setting it
to 'false'. But the configuration is meant to be the primary control and
setting it to 'true' will enable it; the rr-cache directory will be
created as necessary and the user does not have to create it.

When showing the raw timestamp, we format the numeric
seconds-since-epoch into a buffer, followed by the timezone
string. This string has come straight from the commit
object. A well-formed object should have a timezone string
of only a few bytes, but we could be operating on data
pushed by a malicious user.

When we fetch from a remote, we print a status table like:

  From url
   * [new branch]   foo -> origin/foo

We create this table in a static buffer using sprintf. If
the remote refnames are long, they can overflow this buffer
and smash the stack.

Instead, let's use a strbuf to build the string.

The keepcr flag is only used in the split_patches function, which is
only called before a patch application has to stopped for user input,
not after resuming. It is therefore unnecessary to persist the

v1.7.5-rc0~48 (Fix sparse warnings, 2011-03-22) introduced undeclared
