I am not sure if this is a bug, but I find this behaviour unnecessary.

When programs are launched using awesome-menu, they are executed as a child process of a bash shell instead of replacing the shell itself.

More concretely I have the following binding in awesomerc:

key { modkey = {"Mod4"} key = "r" command = "spawn" arg = "cat ~/.apps | awesome-menu -e 'exec ' Execute:"

If I execute pidgin for example, and then perform ps auxf, I get the following output:

myuser 7295 0.0 0.0 3812 1236 ? Ss 13:16 0:00 /bin/bash -c cat ~/.apps | awesome-menu -e 'exec ' Execute:
myuser 7297 0.1 0.9 69332 31612 ? Sl 13:16 0:23 \_ pidgin

The cat command along with the pipe clearly needed a shell, however I would expect the pidgin process to replace the shell process instead of forking and creating a new process.
This task depends upon

Same thing here (using liferea as an example):

naoliv 2249 0.0 0.0 3788 1092 ? Ss May01 0:00 /bin/bash -c find /usr/bin -type f -executable ! -empty | awesome-menu -e 'exec ' Execute:
naoliv 2251 0.0 3.0 163832 64060 ? Sl May01 19:27 \_ /usr/bin/liferea-bin

This is not a bug, really. The default .awesomerc should contain an ampersand after the command, like this:

modkey = {"Mod4"}
key = "F1"
command = "spawn"
arg = "ls -R /usr/share/man/man? | grep .gz | cut -d. -f1 | awesome-menu -e 'xterm -e man ' 'man:' &"

(My Mod4+F1 command, C shell.)

Fact is (as much as I can see, heh), the "spawn" command just executes the shell, the user's default one. whatever put in the arg should abide by that shell's syntax.

typing the command in awesome-menu with "&" solves the problem, but it is kinda bad to type extra-char each time, so i patched awesome-menu.c a little so it adds "&"-char automatically.
works fine for me, though i haven't tested it a lot. the patch is in the attachment
