"T" in these shorthand flags is for "trace", maybe it is a good idea to
follow this convention. On the other side, if blindly follow this rule, size of
shorthand would be gargantuan 4 chars.

Also, from my point of view, it's quite strange to include ustat and do
not include fstatfs, since, well, they are equivalently similar to statfs.
