Re: auto-fill breaks line too early

[Michael Heerdegen]

Hi,


the doc of `fill-paragraph' reveals the mystery:

| If `sentence-end-double-space' is non-nil, then period followed by one
| space does not end a sentence, so don't break a line there.

The default value is t. So, no, it's not a bug.  Customize
`sentence-end-double-space' to nil to change the behavior.
