Instead of setting watches on individual files when a non-empty filespec is given, always watch all the files but just ignore the events from the ones not matching the filespec. This makes the code simpler and fixes several bugs. See #14544. git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@72681 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
