Junio C Hamano 33e8fc8740 usage: do not insist that standard input must come from a file
The synopsys text and the usage string of subcommands that read list
of things from the standard input are often shown like this:

	git gostak [--distim] < <list-of-doshes>

This is problematic in a number of ways:

 * The way to use these commands is more often to feed them the
   output from another command, not feed them from a file.

 * Manual pages outside Git, commands that operate on the data read
   from the standard input, e.g "sort", "grep", "sed", etc., are not
   described with such a "< redirection-from-file" in their synopsys
   text.  Our doing so introduces inconsistency.

 * We do not insist on where the output should go, by saying

	git gostak [--distim] < <list-of-doshes> > <output>

 * As it is our convention to enclose placeholders inside <braket>,
   the redirection operator followed by a placeholder filename
   becomes very hard to read, both in the documentation and in the
   help text.

Let's clean them all up, after making sure that the documentation
clearly describes the modes that take information from the standard
input and what kind of things are expected on the input.

git-mktag(1)
============
NAME
----
git-mktag - Creates a tag object
SYNOPSIS
--------
[verse]
'git mktag'
DESCRIPTION
-----------
Reads a tag contents on standard input and creates a tag object
that can also be used to sign other objects.
The output is the new tag's <object> identifier.
Tag Format
----------
A tag signature file, to be fed to this command's standard input,
has a very simple fixed format: four lines of
object <sha1>
type <typename>
tag <tagname>
tagger <tagger>
followed by some 'optional' free-form message (some tags created
by older Git may not have `tagger` line). The message, when
exists, is separated by a blank line from the header. The
message part may contain a signature that Git itself doesn't
care about, but that can be verified with gpg.
