[PATCH 2/5] doc: convert git-grep synopsis and options to new style

["Jean-Noël Avila via GitGitGadget" <gitgitgadget@gmail.com>]

From: =?UTF-8?q?Jean-No=C3=ABl=20Avila?= <jn.avila@free.fr>

Convert git-grep.adoc from [verse]/single-quote style to the modern
synopsis-block style:

- Replace [verse] with [synopsis] in SYNOPSIS block
- Change 'git grep' to git grep (no single quotes)
- Backtick-quote all OPTIONS terms
- Convert inline man page refs: grep(1) -> `grep`(1)
- Convert inline command refs: 'git diff' -> `git diff`
- Convert prose placeholders: <file> -> _<file>_

---untracked::
+`--untracked`::
 	In addition to searching in the tracked files in the working
 	tree, search also in untracked files.
 
---no-index::

 This option cannot be used together with `--cached` or `--untracked`.
 See also `grep.fallbackToNoIndex` in 'CONFIGURATION' below.
 
---no-exclude-standard::
+`--no-exclude-standard`::
 	Also search in ignored files by not honoring the `.gitignore`
 	mechanism. Only useful with `--untracked`.

 	mechanism.  Only useful when searching files in the current directory
 	with `--no-index`.
 
---recurse-submodules::
+`--recurse-submodules`::
 	Recursively search in each submodule that is active and
 	checked out in the repository.  When used in combination with the
 	_<tree>_ option the prefix of all submodule output will be the name of
 	the parent project's _<tree>_ object.  This option cannot be used together
 	with `--untracked`, and it has no effect if `--no-index` is specified.
 
--a::
---text::
+`-a`::
+`--text`::
 	Process binary files as if they were text.
 
---textconv::
+`--textconv`::
 	Honor textconv filter settings.
 
---no-textconv::
+`--no-textconv`::
 	Do not honor textconv filter settings.
 	This is the default.
 
--i::
---ignore-case::
+`-i`::
+`--ignore-case`::
 	Ignore case differences between the patterns and the
 	files.
 
--I::
+`-I`::
 	Don't match the pattern in binary files.

 	line.
 
---full-name::
