Patch: Doc: clarify effect of KSH_ARRAYS on subscript (I)

[dg1727 <dg1727@xxxxxxxxxxxxxx>]

Hello,

Following is a Git diff of a proposed update to the documentation.

In future, if I have a small item like this to suggest, I intend to try to combine it with other small items so as not to make too much mailing-list traffic.  (I make no promises about this.)

This first minor update is just to try out the process.

 Like `tt(i)', but gives the index of the last match, or all possible
 matching keys in an associative array.  On failure substitutes 0, or
