clojure-in-docstring-p

There is an off-by-one error in clojure-in-docstring-p.

It happens when the first line is zero width!

It happens when the first line is zero width!

Can you elaborate on that? A repro case would be helpful.

Sorry for the terse report! I had a four year old jump on my half-way through.

Reproducible case: Open an empty file in Clojure mode, hit tab. It breaks.

My diagnosis is:

(get-text-property (1- (point-at-eol) 'face)

is illegal since with a empty first line (1- (point-at-eol)) returns 0.
