[PATCH] doc/SubmittingPatches: improve text formatting

[Todd Zullinger <tmz@pobox.com>]

049e64aa50 ("Documentation: convert SubmittingPatches to AsciiDoc",
2017-11-12) changed the `git blame` and `git shortlog` examples given in
the section on sending your patches.

In order to italicize the `$path` argument the commands are enclosed in
plus characters as opposed to backticks.  The difference between the
quoting methods is that backtick enclosed text is not subject to further
expansion.  This formatting makes reading SubmittingPatches in a git
clone a little more difficult.  In addition to the underscores around
`$path` the `--` chars in `git shortlog --no-merges` must be replaced
with `{litdd}`.

Use backticks to quote these commands.  The italicized `$path` is lost
from the html version but the commands can be read (and copied) more
easily by users reading the text version.  These readers are more likely
to use the commands while submitting patches.  Make it easier for them.

I missed this in the initial discussion.  It was mentioned by

That's what I had guessed before I looked back at the list
archives.  I understand the desire to make it clear that $path
isn't a literal value.  I think that it's worth losing that subtle
hint in order to make the plain text SubmittingPatches file a
little easier to read.

Whether the people most likely to be considering sending a patch
for git.git are will read the document from a git clone or the
rendered html output is the main question.  Though even readers of
the installed text file in their packaged git will suffer a bit.

It's great having the document in HTML to aid in sharing it's
guidance with others, no doubt.  I've wanted to symlink to
portions of the document numerous times.  I hope a small change to
make it more legible to those who also like plain text will be
welcome.

I considered using backticks for the commands and then +_$path_+
for the argument.  Maybe that's a reasonable compromise?  I.e.:

-+git blame _$path_+ and +git shortlog {litdd}no-merges _$path_+ would help to
+`git blame` +_$path_+ and `git shortlog --no-merges` +_$path_+ would help to

The text version is still a bit strange with that method, but it
certainly separates "$path" from the rest of the command in both
the text and html output. :)
