[PATCH] use strbuf_complete_line() for adding a newline if needed

[PATCH] use strbuf_complete_line() for adding a newline if needed

[René Scharfe]

Call strbuf_complete_line() instead of open-coding it.  Also remove
surrounding comments indicating the intent to complete a line since
this information is already included in the function name.
