[Nmh-workers] Bash completion

<#secure method=pgpmime mode=sign>
Hello,

When I source /usr/share/doc/nmh-1.3/COMPLETION-BASH I get the following
error:

somehost: ~ > source /usr/share/doc/nmh-1.3/COMPLETION-BASH 
bash: /usr/share/doc/nmh-1.3/COMPLETION-BASH:23: syntax error near unexpected 
token `('
bash: /usr/share/doc/nmh-1.3/COMPLETION-BASH:23: `        \++([a-zA-Z_]) )'

There seem to be a lot of unbalanced parentheses in this file; I have
fixed those I could find (see attached patch).  However after I source
it again I get this error:

bash: have: command not found

The first line of the file is "have show &&"

Is this a portability issue (is "have" a builtin command for some
installations of bash?  I can't find it in any documentation), or am I
not supposed to source it?  How else would I load it?

The zsh completion worked really well, so using mh from the command-line
was a breeze.  However, since switching to bash I have not had
completion and it's now a chore (for when I'm not using Emacs).  

Thanks for any help you can offer,

Joel
