+ Caches the information provided by repo.status() in the file
+ .hg/thgstatus, which can then be read by the overlay shell extension
+ to display overlay icons for directories.
+
+ The file .hg/thgstatus contains one line for each directory that has
+ removed, modified or added files (in that order of preference). Each
+ line consists of one char for the status of the directory (r, m or a),
+ followed by the relative path of the directory in the repo. If the
+ file .hg/thgstatus is empty, then the repo's working directory is
+ clean.
+
+ Specify wait=True to wait until the system clock ticks to the next
+ second before accessing Mercurial's dirstate. This is useful when
+ Mercurial's .hg/dirstate contains unset entries (in output of
+ "hg debugstate"). unset entries happen if .hg/dirstate was updated
+ within the same second as Mercurial updated the respective file in
+ the working tree. This happens with a high probability for example
+ when cloning a repo. The overlay shell extension will display unset
+ dirstate entries as (potentially false) modified. Specifying wait=True
+ ensures that there are no unset entries left in .hg/dirstate when this
+ function exits.
