Briefly, because otherwise ./t7811-grep-open.sh fails when run under
watchman.

This is actually something that I think I'm doing wrong, but I can't see
what the sensible way to do it is.  When we go to write the fs_cache (in
an atexit hook), we use get_fs_cache_file() from environment.c.  This is
a relative path, because all of the other similar paths are.  So if we
have chdired, then we fail.
