So I think this is a nice, simple approach for sites that want it, and
noglob magic can come later (and will not be any harder to implement as
a result of this patch).

Any chance to make use of nd/pathspec-wildcard? It changes the same
code path in match_one. If you base on top of nd/pathspec-wildcard,
all you have to do is assign nowildcard_len to len (i.e. no wildcard
part).

I'd rather keep it separate for now. One, just because they really are
independent topics, and two, because I am actually back-porting it for
GitHub (we are fairly conservative about upgrading our backend git
versions, as most of the interesting stuff happens on the client side; I
cherry-pick critical patches with no regard to the release cycle).

And the resolution is pretty trivial, too. It looks like this:

diff --cc dir.c
index 5c0e5f6,03ff36b..81cb439

--- a/dir.c
+++ b/dir.c

@@@ -1456,14 -1433,10 +1460,18 @@@ int init_pathspec(struct pathspec *path
  
  		item->match = path;
  		item->len = strlen(path);
- 		item->nowildcard_len = simple_length(path);
 -		item->use_wildcard = !limit_pathspec_to_literal() &&
 -				     !no_wildcard(path);
 -		if (item->use_wildcard)
 -			pathspec->has_wildcard = 1;
 +		item->flags = 0;
- 		if (item->nowildcard_len < item->len) {
- 			pathspec->has_wildcard = 1;
- 			if (path[item->nowildcard_len] == '*' &&
- 			    no_wildcard(path + item->nowildcard_len + 1))
- 				item->flags |= PATHSPEC_ONESTAR;
++		if (limit_pathspec_to_literal())
++			item->nowildcard_len = item->len;
++		else {
++			item->nowildcard_len = simple_length(path);
++			if (item->nowildcard_len < item->len) {
++				pathspec->has_wildcard = 1;
++				if (path[item->nowildcard_len] == '*' &&
++				    no_wildcard(path + item->nowildcard_len + 1))
++					item->flags |= PATHSPEC_ONESTAR;
++			}
 +		}
  	}
  
  	qsort(pathspec->items, pathspec->nr,

Not re-indenting the conditional would make the diff more readable, but
I think the resulting code is simpler to read if all of the wildcard
stuff is inside the "else" block.
