help.c: help.autocorrect=never means "do not compute suggestions"

Browse Source 
While help.autocorrect can be set to 0 to decline auto-execution of
possibly mistyped commands, it still spends cycles to compute the
suggestions, and it wastes screen real estate.

Update help.autocorrect to accept the string "never" to just exit
with error upon mistyped commands to help users who prefer to never
see suggested corrections at all.

While at it, introduce "immediate" as a more readable way to
immediately execute the auto-corrected command, which can be done
with negative value.

help.autoCorrect::
Automatically correct and execute mistyped commands after
waiting for the given number of deciseconds (0.1 sec). If more
than one command can be deduced from the entered text, nothing
will be executed. If the value of this option is negative,
the corrected command will be executed immediately. If the
value is 0 - the command will be just shown but not executed.
This is the default.
If git detects typos and can identify exactly one valid command similar
to the error, git will automatically run the intended command after
waiting a duration of time defined by this configuration value in
deciseconds (0.1 sec). If this value is 0, the suggested corrections
will be shown, but not executed. If it is a negative integer, or
"immediate", the suggested command
is run immediately. If "never", suggestions are not shown at all. The
default value is zero.
