 When I run out of disk space while applying the Tor Browser update, it
 tells me it failed but doesn't say why.

 In perfect world it would check there exists enough free space before
 starting the download.

 In my case, I *think* the download was successfully but it ran out of
 space while applying the patches. On subsequent launches it did not
 attempt to redownload it, but continued to fail to apply it. Foolheartedly
 I removed the "0" directory from the updates directory (so that it would
 redownload it) just realization that my disk was filled, so I don't
 actually know if it would've applied the update eventually had I only
 freed up some space.
