You still need to escape # inside the pattern, don't you? As in:

:grep /\#foo/ *

At least, when 'grepprg' is grep (which is the default?). If it's set to
internal, then I can actually search for /#foo/.

Btw, as I was experimenting with grep commands, I have also realised
that a command with -complete=file expands #, but a command without it
does not. So, this is what I've come up with:

command! -nargs=+ Grep call s:grep(<q-args>)

fun s:grep(args)
execute 'silent grep!' shellescape(fnameescape(a:args)) '**/*'
endf

Then, s:grep() will receive '#foo' when I type :Grep #foo. Inside the
function, fnameescape() will escape # again for :grep!, and
shellescape() will escape the input for the shell. I have yet to test
this thoroughly, maybe there are better ways.

The drawback is that the custom command does not expand any path.

Life.

It's worse than that. It makes things fall apart.
