Maybe they do this because they read it in the Git user-manual.

Fix the manual to give them better guidance.

2475770239 Documentation: update implicit "--no-index" behavior in "git diff"
Originally "--no-index" mode triggered for untracked files within the
tracked tree, but with v1.5.6-rc1~41 (Merge branch 'jc/diff-no-no-index,
2008-05-26) the command was fixed to only implicitly trigger when paths
outside the tracked tree are mentioned.

b77134b068 Documentation: expand 'git diff' SEE ALSO section
Point in many directions in the hope of helping the reader find what
is needed more quickly.

This commit also removes the summary attached to the SEE ALSO entry
for difftool, to avoid making the SEE ALSO list too verbose.  If the
reader wants a summary of the commands referred to, she can always
look to the top of the named pages or to the table of contents on the
main git(1) page.

2794ad5244 fast-import: Allow filemodify to set the root
v1.7.3-rc0~75^2 (Teach fast-import to import subtrees named by tree id,
2010-06-30) has a shortcoming - it doesn't allow the root to be set.
Extend this behaviour by allowing the root to be referenced as the
empty path, "".

For a command (like filter-branch --subdirectory-filter) that wants
to commit a lot of trees that already exist in the object db, writing
undeltified objects as loose files only to repack them later can
involve a significant amount of overhead.
(23% slow-down observed on Linux 2.6.35, worse on Mac OS X 10.6)

Fortunately we have fast-import (which is one of the only git commands
that will write to a pack directly) but there is not an advertised way
to tell fast-import to commit a given tree without unpacking it.

This patch changes that, by allowing

	M 040000 <tree id> ""

as a filemodify line in a commit to reset to a particular tree without
any need to parse it.  For example,

	M 040000 4b825dc642 ""

is a synonym for the deleteall command and the fast-import equivalent of

	git read-tree 4b825dc642

d0af3734f1 gitweb: Improve behavior for actionless path_info gitweb URLs
Eli Barzilay noticed that

  http://server/gitweb/project/<commit-sha1>

link goes to 'shortlog' view, while 'commit' view would be more
useful, but that 'shortlog' action is more apropriate for

  http://server/gitweb/project/<commit-sha1>..<other-commit-sha1>

links.

Therefore for the case when we don't have either action, or filename,
or parent hash [base] in path_info-based URL, i.e. for

  http://server/gitweb/project/<object-id>

link, instead of using 'shortlog' view we allow dispatch() subroutine
to detect type of object and use appropriate action (in most case it
would be either 'commit' action, or 'tag', or 'tree' for top
directory).

b90d9b8895 work around buggy S_ISxxx(m) implementations
There are buggy implementations of S_ISxxx(m) macros on some platforms
(e.g. NetBSD).  The issue is that NetBSD doesn't take care to wrap its
macro arguments in parentheses, so on Linux and sane systems we have
S_ISREG(m) defined as something like:

    (((m) & S_IFMT) == S_IFREG)

But on NetBSD:

    ((m & _S_IFMT) == _S_IFREG)

Since a caller in builtin/diff.c called our macro as `S_IFREG | 0644'
this bug introduced a logic error on NetBSD, since the precedence of
bit-wise & is higher than | in C.

349362cc20 xdiff: cast arguments for ctype functions to unsigned char
The ctype functions isspace(), isalnum(), et al take an integer
argument representing an unsigned character, or -1 for EOF.  On
platforms with a signed char, it is unsafe to pass a char to them
without casting it to unsigned char first.

Most of git is already shielded against this by the ctype
implementation in git-compat-util.h, but xdiff, which uses libc
ctype.h, ought to be fixed.

ff9db6c79d On Windows, avoid git-gui to call Cygwin's nice utility
It's a common case for Windows developers to have both Cygwin and msysGit
installed. Unfortunately, some scenarios also require to have Cygwin in PATH.
By default, Cygwin comes with nice.exe, while msysGit does not. Since git-gui
calls nice if it is in PATH, this results in Cygwin's nice.exe being called
from msysGit's git-gui. Mixing Cygwin and msysGit generally is not a good idea,
and in this particular case it causes differences not being correctly detected.
So we only call nice.exe on Windows if it is in the same directory as git.exe.
This way, this work-around does neither affect a pure Cygwin environment, or
the case when nice.exe will be shipped with msysGit at some point in time.

This fixes msysGit issue 394.

be part of the To: addresses in the second patch. Fix this by treating the
to list like the cc list. Have an initial to list come from the command
line, user input and config options. Then build up a to list from each
patch and concatenate the two together before sending the patch. Finally,
reset the list after sending each patch so the To: headers from a patch
don't get used for the next one.
