25.3; Errors in narrowed buffers in CC-mode |

The inception of this bug report can be found at:
https://github.com/josteink/csharp-mode/issues/119
For those too lazy to follow the link, here's the gist: When I press
`RET' at the beginning or end of a narrowed buffer in CC-mode, I see
errors like this:
c-determine-limit: Args out of range: #<buffer dired.c>, 1, 1564
A full backtrace yields something like this:
Debugger entered--Lisp error: (args-out-of-range #<buffer dired.c> 1 1564)
parse-partial-sexp(1 1564)
c-determine-limit(500)
c-guess-basic-syntax()
c-indent-line()
indent-according-to-mode()
electric-indent-post-self-insert-function()
self-insert-command(1)
newline(nil 1)
funcall-interactively(newline nil 1)
call-interactively(newline nil nil)
command-execute(newline)
As you can see from the filename there, the file I was testing this with
was dired.c from the very Emacs source tree (although I have now tested
with various header files, other C files, and of course, C# files).
I initially tested this on a macOS system, but now I have also tested
this on Ubuntu and I see the same issue occurring on both systems (which
are both using Emacs 25.3).
I also noticed that this issue does not occur in Emacs 24.

I've committed the fix to Emacs's emacs-26 branch, and I'm closing the
bug.

Thank you, too!
