Log Message:
Changes 1.7.9.3:
* "git p4" (in contrib/) submit the changes to a wrong place when the
  "--use-client-spec" option is set.
* The config.mak.autogen generated by optional autoconf support tried
  to link the binary with -lintl even when libintl.h is missing from
  the system.
* When the filter driver exits before reading the content before the
  main git process writes the contents to be filtered to the pipe to
  it, the latter could be killed with SIGPIPE instead of ignoring
  such an event as an error.
* "git add --refresh <pathspec>" used to warn about unmerged paths
  outside the given pathspec.
* The bulk check-in codepath in "git add" streamed contents that
  needs smudge/clean filters without running them, instead of punting
  and delegating to the codepath to run filters after slurping
  everything to core.
* "git branch --with $that" assumed incorrectly that the user will never
  ask the question with nonsense value in $that.
* "git bundle create" produced a corrupt bundle file upon seeing
  commits with excessively long subject line.
* When a remote helper exits before reading the blank line from the
  main git process to signal the end of commands, the latter could be
  killed with SIGPIPE. Instead we should ignore such event as a
  non-error.
* The commit log template given with "git merge --edit" did not have
  a short instructive text like what "git commit" gives.
* "git rev-list --verify-objects -q" omitted the extra verification
  it needs to do over "git rev-list --objects -q" by mistake.
* "gitweb" used to drop warnings in the log file when \ 
"heads" view is
  accessed in a repository whose HEAD does not point at a valid
  branch.
* An invalid regular expression pattern given by an end user made
  "gitweb" to return garbled response.
