git-svn: Document branches with at-sign(@).

git svn sometimes creates branches with an at-sign in the name
(branchname@revision). These branches confuse many users and it is a FAQ
why they are created. Document when git svn creates them.

git-svn: Recommend use of structure options.

Document that when using git svn, one should usually either use the
directory structure options to import branches as branches, or only
import one subdirectory. The default behaviour of cloning all branches
and tags as subdirectories in the working copy is usually not what the
user wants.

.mailmap: match up some obvious names/emails

This patch updates git's .mailmap in cases where multiple
names are matched to a single email. The "master" name for
each email was chosen by:

  1. If the only difference is in the presence or absence
     of accented characters, the accented form is chosen
     (under the assumption that it is the natural spelling,
     and accents are sometimes stripped in email).

  2. Otherwise, the most commonly used name is chosen.

  3. If all names are equally common, the most recently used name is
     chosen.

.mailmap: fix broken entry for Martin Langhoff

Commit adc3192 (Martin Langhoff has a new e-mail address,
2010-10-05) added a mailmap entry, but forgot that both the
old and new email addresses need to appear for one to be
mapped to the other (i.e., we do not key mailmap emails by
name).

.mailmap: normalize emails for Linus Torvalds

Linus used a lot of different per-machine email addresses in
the early days. This means that "git shortlog -nse" does not
aggregate his counts, and he is listed well below where he
should be (8th instead of 3rd).

contrib: update stats/mailmap script

This version changes quite a few things:

  1. The original parsed the mailmap file itself, and it did
     it wrong (it did not understand entries with an extra
     email key).

     Instead, this version uses git's "%aE" and "%aN"
     formats to have git perform the mapping, meaning we do
     not have to read .mailmap at all, but still operate on
     the current state that git sees (and it also works
     properly from subdirs).

  2. The original would find multiple names for an email,
     but not the other way around.

     This version can do either or both. If we find multiple
     emails for a name, the resolution is less obvious than
     the other way around. However, it can still be a
     starting point for a human to investigate.

  3. The original would order only by count, not by recency.

     This version can do either. Combined with showing the
     counts, it can be easier to decide how to resolve.

  4. This version shows similar entries in a blank-delimited
     stanza, which makes it more clear which options you are
     picking from.

index-format.txt: clarify what is "invalid"

A cache-tree entry with a negative entry count is considered invalid
by the current Git; it records that we do not know the object name
of a tree that would result by writing the directory covered by the
cache-tree as a tree object.

Clarify that any entry with a negative entry count is invalid, but
the implementations must write -1 there. This way, we can later
decide to allow writers to use negative values other than -1 to
encode optional information on such invalidated entries without
harming interoperability; we do not know what will be encoded and
how, so we keep these other negative values as reserved for now.

Documentation: don't link to example mail addresses

Email addresses in documentation are converted into mailto: hyperlinks
in the HTML output and footnotes in man pages.  This isn't desirable for
cases where the address is used as an example and is not valid.

Particularly annoying is the example "jane@laptop.(none)" which appears
in git-shortlog(1) as "jane@laptop[1].(none)", with note 1 saying:

	1. jane@laptop
	   mailto:jane@laptop

Fix this by escaping these email addresses with a leading backslash, to
prevent Asciidoc expanding them as inline macros.

In the case of mailmap.txt, render the address monospaced so that it
matches the block examples surrounding that paragraph.
