I didn't notice it has no quote.  It could be added to the example
before (concat ...) to demonstrate this feature.

Strictly speaking, there is no condition.  On the other hand, it
correctly describes the behavior.  In any case, wording could be
improved, e.g.

"It can be any expression, not just a string.  It is evaluated
to the command string before `compile' prompts for the command.
When the value of the command specified at the command prompt is
not the same as evaluated from the expression, then this variable
gets overwritten with the value of the last specified command string."

I see also that this feature conflicts with the defcustom type
of this variable which currently is :type 'string.  It should
be changed to :type 'sexp.
