packagesuppliers/filesystem.d: Only glob versions of a package_id

[the-horo]

When looking for versions of a package don't include other packages that start with the same name as the queried package. This is done by requiring that the first character after the - is a digit.

If a directory contains the files botan-1.zip and botan-math-2.zip the current implementation would report both 1 and math-2 as candidates followed by an error that math-2 is not a valid version:

$ ls /tmp/mytest
botan-1.13.4.zip  botan-1.13.5.zip  botan-1.13.6.zip  botan-math-1.0.3.zip  botan-math-1.0.4.zip  repo

$ dub --vverbose --cache=local --registry=file:///tmp/mytest/ --skip-registry=all fetch [email protected]
Note: Failed to determine version of package repo at .. Assuming ~master.
Entry: /tmp/mytest/botan-math-1.0.3.zip

I haven't hit it yet but can

Line 33 in 60d9cee

enforce(to!string(p.head)[$-4..$] == ".zip");

go from an enforce to a continue? There shouldn't be a problem if the directory contains misc files that start with the same name as a package.

can enforce(to!string(p.head)[$-4..$] == ".zip") go from an enforce to a continue?

Yes, but I think we can make it even simpler:
