In the case at hand we have mWh and mAh, which measure different

don't.
You just need to know the voltage of the battery, what else?
And it would be nice to also allow for power supply devices that use
other, incompatible units like "percent" or "minutes" or "hand crank
revolutions".
Do such batteries exist at the moment, or are you just speculating?
I have seen joules (or mJ) on a laptop. Yes, it was Windows, but I bet
the report came from hardware. Some vendor getting anal about metric?

don't quite see how a battery could report remaining energy in time
units, as power consumption varies over time. Hand crank revolutions
wouldn't be a very useful unit either, unless you know how much energy
a revolution provides, and then you can just convert it. Percent would
make some sense, but you can only express the remaining energy this way,
not the total. And if you know the total in mAh or mWh, you can multiply
by the percentage and you get the remaining energy in the same unit.

Obscure bug of 2004: BASH BUFFER OVERFLOW - if bash is being run by a
normal user and is setuid root, with the "vi" line edit mode selected,
and the character set is "big5," an off-by-one errors occurs during
wildcard (glob) expansion.
