Also the CursorHold event seems to fire repeatedly, contradicting my understanding of the automatic command and its behavior on UNIX?! This behavior doesn't occur when I use the integration with my `shell.vim` plug-in.
* I might have found a bug in Vim: The tag `easytags#highlight_cmd` was correctly being highlighted by my plug-in (and was indeed included in my tags file) even though I couldn't jump to it using `Ctrl-]`, which caused:
