I'm afraid it's just pretending to work. The default query parser very
rarely reports an error, so it's actually just searching for the word
"list", anywhere. It might approximate what you want. Compare:

    ╭─ motzkin:~
    ╰─% NOTMUCH_DEBUG_QUERY=t notmuch count --exclude=false  '(List *)'
    Query string is:
    (List *)
    Exclude query is:
    Query()
    Final query is:
    Query((Tmail AND (list@1 OR Glist@1 OR Klist@1 OR Klist@1 OR Qlist@1 OR Qlist@1 OR Plist@1 OR XPROPERTYlist@1 OR XFOLDER:list@1 OR XFROMlist@1 OR XTOlist@1 OR XATTACHMENTlist@1 OR XMIMETYPElist@1 OR XSUBJECTlist@1 OR XUList:list@1)))

The big "OR" is how we implement "find this word anywhere"

    ╭─ motzkin:~
    ╰─% NOTMUCH_DEBUG_QUERY=t notmuch count --exclude=false --query=sexp '(List *)'
    Query string is:
    (List *)
    Exclude query is:
    Query()
    Final query is:
    Query((Tmail AND (<alldocuments> AND WILDCARD SYNONYM XUList:)))
    555917

Here the sexp query parser is generating "WILDCARD SYNONYM XUList:" from
'(List *)'

Apparently I have a fair number of mailing list messages that don't
mention the word List in the content.

Notmuch doesn't index file names, only directory names (it stores the
file names so they can be printed, but not as document terms in the
database).

You don't need, or want the leading / here; the directories (folders)
are indexed relative to the mail root. The following should work, but
won't match the individual file.

     notmuch search --output=files 'path:"~ml/linux-l@mlists.in-berlin.de/cur/"'

I don't know precisely happens for you, but try 

    notmuch count path:~ml/linux-l@mlists.in-berlin.de/cur/1060758271.3350_0.pit-to-be-deleted

in place of reindex. I think you will see the answer is 0, which means
reindex won't do anything.

This does not surprise me, as explained above.

Unfortunately there is no way to escape, as filenames are just not
supported in queries. They could be, but it would require a complete
redesign of the database schema. That might happen at some point, but it
could be a while.
