This is already implemented with a default cutoff of 80 characters.  The help text for get_first_help_sentence is:

 -- TEXT = get_first_help_sentence (NAME)
 -- TEXT = get_first_help_sentence (NAME, MAX_LEN)
 -- [TEXT, STATUS] = get_first_help_sentence (...)
     Return the first sentence of a function's help text.

     The first sentence is defined as the text after the function
     declaration until either the first period (".")  or the first
     appearance of two consecutive newlines ("\n\n").  The text is
     truncated to a maximum length of MAX_LEN, which defaults to 80.
