commit 314cc5f0dd48c047e660f45aaaf4e86675ab5d74
Author: Jan Engelhardt <jengelh@xxxxxxxxxx>
Date: Tue May 6 19:47:33 2008 +0200
manpages: consistent syntax
In the manpages, bold is used to denote characters the user has to
enter verbatim, italic denotes placeholders and non-highlighted
pieces are used as a structure: "[]" specifying an optional part,
"{}" a mandatory part, with "|" used for alternations. The "!" for
negation is better supported before the option than after it, too.
The patch makes a few files consistent with this style already used
in manpages.
