Thanks, installed and closed.

A NEWS entry for this change has no "---" indication that means
it should be documented in the manual before the next release when
the functionality is stabilized and there are no more code changes.

Within dired, I want to run a shell command asynchronously on
multiple files individually. Say, most specifically I tried to
watch the postscript files foo.ps and bar.ps with gv.

So I mark foo.ps and bar.ps in the dired buffer and hit
& gv ?

In the buffer *Async Shell Command* this gives me the error message

/bin/bash: -c: line 0: syntax error near unexpected token `;'
/bin/bash: -c: line 0: `gv foo.ps &;gv bar.ps'

I get the same error message with the command dired-do-shell-command using
! gv ? &

I am not the most experienced bash expert. But it seems that bash
doesn't like the combination `&;'. Note also that there is no `&'
for `gv bar.ps'.

In a tty
$ gv foo.ps & gv bar.ps &
works fine for me (giving me what I expect to get within dired).

Am I misunderstanding the docstrings of dired-do-shell-command and
dired-do-async-shell-command (which are a bit confusing for me
concerning how to run a shell command on multiple files) or is there
a bug in the code?
