[PATCH v3 0/3] doc: introducing synopsis para

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

Following several issues with the way the formatting of synopsis is done in
the manpages that were recently reworked, this patch series introduces the
processing of a new custom paragraph attribute 'synopsis'. Additionally, as
s macro is introduce to apply the same rules freely in the text.

This extension is added to asciidoc and asciidoctor and lets write the
synopsis of the commands without any typeset. The git-init and git-clone
manpages are converted to this new system.

Changes since V1:

 * switch to sed for asciidoc filter and refine the regex for support under
   macOS

Changes since V2:

 * introduce the s macro to freely apply synopsis styling wherever needed,
   without formatting hassle.

     +-- ++ssh://++{startsb}__<user>__++@++{endsb}__<host>__{startsb}++:++__<port>__{endsb}++/++__<path-to-git-repo>__

     ++- s:["ftp[s]://<host>[:<port>]/<path-to-git-repo>"]
     + 
     + An alternative scp-like syntax may also be used with the ssh protocol:
     + 
     +-- {startsb}__<user>__++@++{endsb}__<host>__++:/++__<path-to-git-repo>__
     ++- s:["[<user>@]<host>:/<path-to-git-repo>"]

     + This syntax is only recognized if there are no slashes before the
     + first colon. This helps differentiate a local path that contains a
     +@@ Documentation/urls.txt: colon. For example the local path `foo:bar` could be specified as an
     + absolute path or `./foo:bar` to avoid being misinterpreted as an ssh
     + url.

     ++- s:["[<user>@]<host>:~<user>/<path-to-git-repo>"]
     + 
     + For local repositories, also supported by Git natively, the following
     + syntaxes may be used:
     + 
     + - `/path/to/repo.git/`
     +-- ++file:///path/to/repo.git/++
     ++- `file:///path/to/repo.git/`

     ++- s:["<transport>::<address>"]
