Subject: bug#35967: [PATCH] avoid flyspell error if point is at bob
Date: Tue, 28 May 2019 15:43:53 -0500 [thread overview]
Message-ID: <87h89e8g3a.fsf@gmail.com> (raw)
[-- Attachment #1: Type: text/plain, Size: 192 bytes --]
Hello -
The attached patch avoids an args-out-of-range error (from
`get-text-property') if `flyspell-prog-mode' is on and point is in a
comment at the beginning of the buffer.
Thanks,
Alex

Subject: [PATCH] Avoid a flyspell error if point is at beginning of buffer
* lisp/textmodes/flyspell.el (flyspell-generic-progmode-verify):
Check if point is at bob. This prevents an error when e.g.
'flyspell-auto-correct-word' gets called with point at the
beginning of the buffer.
