testing a fix for ignoring hidden files

@jfairley 

Here are the changes I asked Ryan to test.  See anything amiss here?
```
java.lang.String
public boolean startsWith(@org.jetbrains.annotations.NotNull String prefix)
Tests if this string starts with the specified prefix.

Parameters:
prefix - the prefix.

Returns:
true if the character sequence represented by the argument is a prefix of the character sequence represented by this string; false otherwise. Note also that true will be returned if the argument is an empty string or is equal to this String object as determined by the equals(Object) method.

Since:
1. 0
