Note that in the shell command, the SHELL does the wildcard expansion.
When you use call-process, there is no shell involved, and hence no
wildcard expansion.

That is, when you type "mv * /tmp" then the shell will process this
command with wildcard expansion, giving, say, "mv a b c /tmp".  And then
the `mv' program will be executed with the four arguments `a', `b', `c',
and `/tmp'.

>From Lisp, you can do (shell-command "mv * /tmp") to get the effect you
want, or maybe

(call-process "mv" ... "/bin/sh" ... "-c" "mv * /tmp")

This is the same as doing the following from the shell:

/bin/sh -c 'mv * /tmp'

So, to make a long story short, it's not a bug.

Be indiscrete.  Do it continuously.
