[PATCH 1/2] git-archive: add '-o' as a alias for '--output'

[Dmitry Potapov <dpotapov@gmail.com>]

The '-o' option is commonly used in many tools to specify the output file.
Typing '--output' every time is a bit too long to be a practical alternative
to redirecting output. But specifying the output name has the advantage of
making possible to guess the desired output format by filename extension.

PS I resend this patch because I forgot to include the git mailing list when
I sent it before. Sorry for inconvinience...
