The EC console input handling code is being enhanced to accept
abbreviated command names.
If the abbreviation is unique, the appropriate command is used, if the
abbreviation is ambiguous, the command is handled as nonexistent. The
error message is being modified to mention that the command either
does not exist or is ambiguous.
This change also makes it impossible to have command names matching
the beginning of other command names. Two such cases are being fixed
(`ch' renamed to `chan' and `thermal' renamed to 'thermalconf').
BUG=none
TEST=manual
. program the new EC image. Try entering at the console:
> h
Command 'h' either not found or ambiguous.
Command returned error 1
> he
