remove duplicate check

[zooltd]

the function config.PathsIgnore would be called twice each time a filepath is checked

This is intended, the first check acts as a fast-return pattern.

For example, if the ignore paths include .git/** (or .git), the entire .git folder will be ignored without listing all files recursively under .git and perform ignoring logic, which saves a lot of time
