cat-file doc: document that -e will return some output
The -e option added in 7950571ad7 ("A few more options for git-cat-file", 2005-12-03) has always errored out with message on stderr saying that the provided object is malformed, like this: $ git cat-file -e malformed; echo $? fatal: Not a valid object name malformed 128 A reader of this documentation may be misled into thinking that if ! git cat-file -e "$object" [...] as opposed to: if ! git cat-file -e "$object" 2>/dev/null [...] is sufficient to implement a truly silent test that checks whether some arbitrary $object string was both valid, and pointed to an object that exists.
