/*
* Pathname classifications.
*
* The daemon classifies the pathnames that it receives from file
* system notification events into the following categories and uses
* that to decide whether clients are told about them. (And to watch
* for file system synchronization events.)
*
* The client should only care about paths within the working
* directory proper (inside the working directory and not ".git" nor
* inside of ".git/"). That is, the client has read the index and is
* asking for a list of any paths in the working directory that have
* been modified since the last token. The client does not care about
* file system changes within the .git directory (such as new loose
* objects or packfiles). So the client will only receive paths that
* are classified as IS_WORKDIR_PATH.
*
* The daemon uses the IS_DOT_GIT and IS_GITDIR internally to mean the
* exact ".git" directory or GITDIR. If the daemon receives a delete
* event for either of these directories, it will automatically
* shutdown, for example.
*
* Note that the daemon DOES NOT explicitly watch nor special case the
* ".git/index" file. The daemon does not read the index and does not
* have any internal index-relative state. The daemon only collects
* the set of modified paths within the working directory.
