When we try to "git mv" over an existing file, the error
message is fairly informative:
$ git mv one two
fatal: destination exists, source=one, destination=two
When the user forces the overwrite, we give a warning:
$ git mv -f one two
warning: destination exists; will overwrite!
This is less informative, but still sufficient in the simple
rename case, as there is only one rename happening.
But when moving files from one directory to another, it
becomes useless:
$ mkdir three
$ touch one two three/one
$ git add .
$ git mv one two three
fatal: destination exists, source=one, destination=three/one
$ git mv -f one two three
warning: destination exists; will overwrite!
The first message is helpful, but the second one gives us no
clue about what was overwritten. Let's mention the name of
the destination file:
$ git mv -f one two three
warning: overwriting 'three/one'

If you try to "git mv" multiple files onto another
non-directory file, you confusingly get the "usage" message:
$ touch one two three
$ git add .
$ git mv one two three
usage: git mv [options] <source>... <destination>
[...]
From the user's perspective, that makes no sense. They just
gave parameters that exactly match that usage!
This behavior dates back to the original C version of "git
mv", which had a usage message like:
usage: git mv (<source> <destination> | <source>... <destination>)
This was slightly less confusing, because it at least
mentions that there are two ways to invoke (but it still
isn't clear why what the user provided doesn't work).
Instead, let's show an error message like:
$ git mv one two three
fatal: destination 'three' is not a directory
We could leave the usage message in place, too, but it
doesn't actually help here. It contains no hints that there
are two forms, nor that multi-file form requires that the
endpoint be a directory. So it just becomes useless noise
that distracts from the real error.

The code for a verbose flag has been here since "git mv" was
converted to C many years ago, but actually getting the "-v"
flag from the command line was accidentally lost in the
transition.

The "x"-prefixed versions of strdup, malloc, etc. will check whether the
allocation was successful and terminate the process otherwise.
A few uses of malloc were left alone since they already implemented a
graceful path of failure or were in a quasi external library like xdiff.
Additionally, the call to malloc in compat/win32/syslog.c was not modified
since the syslog() implemented there is a die handler and a call to the
x-wrappers within a die handler could result in recursion should memory
allocation fail. This will have to be addressed separately.

This shrinks the top-level directory a bit, and makes it much more
pleasant to use auto-completion on the thing. Instead of
[torvalds@nehalem git]$ em buil<tab>
Display all 180 possibilities? (y or n)
[torvalds@nehalem git]$ em builtin-sh
builtin-shortlog.c builtin-show-branch.c builtin-show-ref.c
builtin-shortlog.o builtin-show-branch.o builtin-show-ref.o
[torvalds@nehalem git]$ em builtin-shor<tab>
builtin-shortlog.c builtin-shortlog.o
[torvalds@nehalem git]$ em builtin-shortlog.c
you get
[torvalds@nehalem git]$ em buil<tab> [type]
builtin/ builtin.h
[torvalds@nehalem git]$ em builtin [auto-completes to]
[torvalds@nehalem git]$ em builtin/sh<tab> [type]
shortlog.c shortlog.o show-branch.c show-branch.o show-ref.c show-ref.o
[torvalds@nehalem git]$ em builtin/sho [auto-completes to]
[torvalds@nehalem git]$ em builtin/shor<tab> [type]
shortlog.c shortlog.o
[torvalds@nehalem git]$ em builtin/shortlog.c
which doesn't seem all that different, but not having that annoying
break in "Display all 180 possibilities?" is quite a relief.
NOTE! If you do this in a clean tree (no object files etc), or using an
editor that has auto-completion rules that ignores '*.o' files, you
won't see that annoying 'Display all 180 possibilities?' message - it
will just show the choices instead. I think bash has some cut-off
around 100 choices or something.
So the reason I see this is that I'm using an odd editory, and thus
don't have the rules to cut down on auto-completion. But you can
simulate that by using 'ls' instead, or something similar.
