This is useful for plugins like dotbot-if [1] that want to instantiate
their own Dispatcher. Previously, the Dispatcher found the set of
available plugins on its own, but as of
b5499c7dc5, this was changed so that
plugins are passed in.
Given that it has been over two years since this behavior has been
broken/changed, reverting to the previous behavior of having the
Dispatcher auto-load plugins might not be ideal, which is why this patch
instead makes the set of plugins available via the Context for plugins
to use.
This was reported in the Dotbot repository [2], and earlier in dotbot-if
[3]. dotbot-if is currently using a workaround [4] that was originally
implemented in dotbot-ifplatform [5].

This patch simplifies the implementation, removing special-case handling
for the cases of zero matches and one match. Instead, any situation
where `glob: true` is specified and the path contains a glob character
(any of "?", "*", or "[") is treated as a glob case. The reason we check
both `use_glob` and `_has_glob_chars()` is to more gracefully handle the
case where the user has enabled globs by default, but most links do not
contain glob characters and should not be treated as globs.
Note that this does NOT port the following command over:
```shell
git config --global protocol.file.allow always
```
Doing so would change the git configuration of users running
the unit tests locally, and this is not an acceptable outcome.
Instead, the git configuration is modified at the CLI using
the `-c protocol.file.allow=always` argument to accomplish
the same thing without side effects.
The fix for this Git security issue [1] involved disabling the local
clone optimization when the repository contains symbolic links. The
security fix broke this particular test; this patch works around the
fix.
