[PATCH] log doc: the argument to --encoding is not optional

[Jonathan Nieder <jrnieder@gmail.com>]

 $ git log --encoding
 fatal: Option '--encoding' requires a value
 $ git rev-list --encoding
 fatal: Option '--encoding' requires a value

The argument to --encoding has always been mandatory.  Unfortunately
manpages like git-rev-list(1), git-log(1), and git-show(1) have
described the option's syntax as "--encoding[=<encoding>]" since it
was first documented.  Clarify by removing the extra brackets.
