This is somewhat at odds with the UX upsides from having fsmonitor enabled, since fsmonitor will be here to take care of mitigating the performance downsides from those untracked files. I considered just suppressing that piece of advice entirely for repositories with fsmonitor disabled, but I decided to replace it with another piece of advice instead, letting the user know that this run may have been slow, but the next ones should be faster. Of course, please let me know if the phrasing can be improved. To keep consistent with other pieces of advice, this new one can be hidden with a new advice.statusFsmonitor config. If the repository does not have fsmonitor enabled, or if the new piece of advice is hidden by config, the behavior falls back to today's behavior: show the message advising to ignore untracked files, as long as it wasn't disabled with the existing advice.statusUoption config. Test-wise, I tried to figure out ways to mock the behavior of a slow git-status, but I couldn't figure it out, so I could use some advice. I tracked down Commit 6a38ef2ced (status: advise to consider use of -u when read_directory takes too long, 2013-03-13), and it also didn't have tests, so I'm questioning whether it can in fact be reasonably done. Thanks in advance for any guidance.
