A Cool New Command: howmany

I wanted to know how many abbrevs I had defined in the file I use to store all my abbrevs. The number of abbrevs correspond to the number of lines in the files that begin with (define-abbrev. But it is not as simple as counting the number of lines in the file itself because there are more than just those kinds of lines. I tried narrowing but there are some comments intermingled with define-abbrev lines. Finally, I asked chatGPT how to do this from Emacs and it recommended a command I never knew existed: how-many. It does exactly what I need: it prints the count of lines that match a given regular expression. I simply invoked how many and gave it the regexp ^(define-abbrev and voilà. As of writing this, I have a whopping 1574 abbrevs.
