Issue 882: add standard hook to reject text files with CRLF.
While the win32text extension does LF <-> CRLF conversion, and will issue a
warning in case a file already in the repository uses CRLF, it provides no
mechanism for verifying that incoming changes use LF. In a large development
team with some Windows users, it is virtually guaranteed that someone will
forget to set up the encode filter correctly and accidentally check in a file
using CRLF, which can cause warnings for other Windows users when they next
fetch changes. Since this is a general problem it is desirable to have a
pre-commit (or -push) hook available to reject such accidents earlier rather
than trying to fix them up after the fact.

#!/bin/sh

hg init
echo a > a
hg ci -Amadd

chmod +x a
hg ci -mexecutable

hg up 0
rm a
ln -s symlink a
hg ci -msymlink

hg merge

echo % symlink is left parent, executable is right

if [ -L a ]; then
    echo a is a symlink
    readlink a
elif [ -x a ]; then
    echo a is executable
fi

hg update -C 1
hg merge

echo % symlink is right parent, executable is left

if [ -L a ]; then
    echo a is a symlink
    readlink a

    echo a is executable
