MSys2 has a slightly different notion of what constitutes a tty than the Microsoft C runtime. The former knows whether stdin/stdout/stderr was redirected or not, while the latter looks for a Win32 Console. In particular when we want to know whether to spawn a pager or not, we would rather want to know what MSys2 thinks. We are about to introduce a change to the msys2-runtime that sets an environment variable MSYS_TTY_HANDLES to a list of Win32 handles that correspond to stdin/stdout/stderr, respectively, *but skips* handles that MSys2 does not think are terminals. This commit handles that input to augment the isatty() function to return 1 also when MSYS_TTY_HANDLES contains the corresponding handle. The only time when Git needs to know whether a Console is attached or not is when winansi.c is asked to Do Its Thing, therefore we refrain from overriding isatty there. Note: this was an issue with MSys1-based Git for Windows, too, hidden by the fact that Git for Windows used `cmd.exe` as a terminal -- which is backed by a real Win32 Console. Had MSys1 used, say, rxvt as its default terminal, the symptom would have been that "git log" does not spawn a pager by default but instead outputs the entire history (without color coding, too). In MSys2, the default terminal is mintty, therefore we finally could not avoid to address the issue. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de>

Git - the stupid content tracker
////////////////////////////////////////////////////////////////
"git" can mean anything, depending on your mood.
- random three-letter combination that is pronounceable, and not
actually used by any common UNIX command. The fact that it is a
mispronunciation of "get" may or may not be relevant.
- stupid. contemptible and despicable. simple. Take your pick from the
dictionary of slang.
- "global information tracker": you're in a good mood, and it actually
works for you. Angels sing, and a light suddenly fills the room.
- "goddamn idiotic truckload of sh*t": when it breaks
Git is a fast, scalable, distributed revision control system with an
unusually rich command set that provides both high-level operations
and full access to internals.
Git is an Open Source project covered by the GNU General Public
License version 2 (some parts of it are under different licenses,
compatible with the GPLv2). It was originally written by Linus
Torvalds with help of a group of hackers around the net.
Please read the file INSTALL for installation instructions.
See Documentation/gittutorial.txt to get started, then see
Documentation/giteveryday.txt for a useful minimum set of commands, and
Documentation/git-commandname.txt for documentation of each command.
If git has been correctly installed, then the tutorial can also be
read with "man gittutorial" or "git help tutorial", and the
documentation of each command with "man git-commandname" or "git help
commandname".
CVS users may also want to read Documentation/gitcvs-migration.txt
("man gitcvs-migration" or "git help cvs-migration" if git is
installed).
Many Git online resources are accessible from http://git-scm.com/
including full documentation and Git related tools.
The user discussion and development of Git take place on the Git
mailing list -- everyone is welcome to post bug reports, feature
requests, comments and patches to git@vger.kernel.org (read
Documentation/SubmittingPatches for instructions on patch submission).
To subscribe to the list, send an email with just "subscribe git" in
the body to majordomo@vger.kernel.org. The mailing list archives are
available at http://news.gmane.org/gmane.comp.version-control.git/,
http://marc.info/?l=git and other archival sites.
The maintainer frequently sends the "What's cooking" reports that
list the current status of various development topics to the mailing
list. The discussion following them give a good reference for
project status, development direction and remaining tasks.
