Pattern for `find` requires search directory prefix

Reporting this as a note. @Gabriel439 remind me to put a PR in for this sometime. Here's the problem:

```
find (decimal *> ".md") "./md"
````
Is my first intuition for searching for all markdown files with a decimal only name in a given directory. However this Pattern fails because it is required to match the entire path. However, the following works

```
find ("./md/" *> decimal *> ".md") "./md"
```
This seems counter-intuitive to what find should be doing: matching against only the basename of a file as apposed to the relative path from the CWD.
