:line eater, the: [USENET] n. 1. A bug in some now-obsolete
versions of the netnews software that used to eat up to BUFSIZ
bytes of the article text. The bug was triggered by having the
text of the article start with a space or tab. This bug was
quickly personified as a mythical creature called the `line
eater', and postings often included a dummy line of `line eater
food'. Ironically, line eater `food' not beginning with a space or
tab wasn't actually eaten, since the bug was avoided; but if there
*was* a space or tab before it, then the line eater would eat
the food *and* the beginning of the text it was supposed to be
protecting. The practice of `sacrificing to the line eater'
continued for some time after the bug had been {nailed to the
wall}, and is still humorously referred to. The bug itself is
still (in mid-1991) occasionally reported to be lurking in some
mail-to-netnews gateways. 2. See {NSA line eater}.
