In GNU Emacs 19.27.1 (sparc-sun-sunos4.1.1) of Mon Oct 10 1994 on ptolemy
If the matching open parenthesis (or other matching open character) is
the only character on a line at the beginning of the buffer, blink-
matching-paren gets an error because it tries to move past the
beginning of the buffer.
To reproduce: In an empty *scratch* type "(" and enough carriage
returns to scroll the "(" off the screen, then type ")".
A related error occurs when the first line has all blanks before the
matching open. To reproduce, type " (" on the first line of scratch,
enough returns to scroll it off, and ")". Blink-matching-paren will claim
that the ")" matches "(...(".
The problem actually came up when I was trying to eliminate blank
lines by matching the string "[^J]+". When I typed that into the
minibuffer, I got the "beginning of buffer" error.
