It's not only suboptimal but simply wrong. getpwuid gives at best the
initial home directory, and even there it is only a guess. (If you are
looking for some home directory of a different user it might be a good
guess). But using getpwuid(getuid())->pw_dir if HOME is set is a serious
mistake, as you throw out the good value for some almost but not quite
totally unrelated value.
