doc/Makefile: ensure C locale

The man pages can actually be translated by building them in a
different locale. However, the man pages contain internal links to
certain sections, and when the section titles are translated, the
links change too. So it is currently not recommended to build the man
pages in anything by the "C" locale.

#!/bin/sh

hg init repo
cd repo

echo line 1 > foo
hg ci -qAm 'add foo' -d "1000000 0"

# copy foo to bar and change both files
hg cp foo bar
echo line 2-1 >> foo
echo line 2-2 >> bar
hg ci -m 'cp foo bar; change both' -d "1000000 0"

# in another branch, change foo in a way that doesn't conflict with
# the other changes
hg up -qC 0
echo line 0 > foo
hg cat foo >> foo
hg ci -m 'change foo' -d "1000000 0"

# we get conflicts that shouldn't be there
hg merge -P
hg merge --debug

echo "-- foo --"
cat foo

echo "-- bar --"
cat bar
