'''Rewrite the file .hg/thgstatus
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.
