remote-hg: always normalize paths

Apparently Mercurial can have paths such as 'foo//bar', so normalize all
paths.

completion: fix completing args of aliased "push", "fetch", etc.

Some commands need the first word to determine the actual action that is
being executed, however, the command is wrong when we use an alias, for
example 'alias.p=push', if we try to complete 'git p origin ', the
result would be wrong because __git_complete_remote_or_refspec() doesn't
know where it came from.

So let's override words[1], so the alias 'p' is override by the actual
command, 'push'.

prompt: fix missing file errors in zsh

zsh seems to have a bug while redirecting the stderr of the 'read'
command:

    % read foo 2>/dev/null <foo
    zsh: no such file or directory: foo

Which causes errors to be displayed when certain files are missing.
Let's add a convenience function to manually check if the file is
readable before calling "read".

config.c: mark die_bad_number as NORETURN

This can help avoid -Wuninitialized false positives in
git_config_int and git_config_ulong, as the compiler now
knows that we do not return "ret" if we hit the error
codepath.
