Have a very large document. Sentences end with a period and a space. Want
to change this to a period and space space. I have been able to FIND the
sequence with ".space[A-Z]" but have not been able to insert the extra
period. Note that I only want to insert the extra space when and if the
following character after the space is a capital Alpha. Some entries in the
document are in the form of ".space#" For example, See spot run.spaceHow now
brown cow. TO See spot run.spacespaceHow now brown cow.

Thanks,
