Since the manpages are written by the git project only, I think it's
more appropriate to address the git mailing list only. [pruning other

That's because of the way other manpages have to be referenced. Let me
include a snippet from the manpage to clarify:

| HIGH-LEVEL COMMANDS (PORCELAIN)
|       We separate the porcelain commands into the main commands and
|       some ancillary user utilities.
|
|   Main porcelain commands
|       git-add(1)
|           Add file contents to the index.

Here, "git-add(1)" is written in one word because otherwise it's not a
valid reference to another manpage. The only alternative is that we
rename the manpage to "add"... but people probably won't like git
polluting the manpage namespace that way, and "add" by itself isn't a
valid command anyway.

If you look at "man git-add", you'll see that the synopsis given there
shows the right way to invoke the command:

| NAME
|       git-add - Add file contents to the index
| 
| SYNOPSIS
|       git add [-n] [-v] [--force | -f] [--interactive | -i]
|                [--patch | -p] [--edit | -e] [--all | [--update | -u]]
|                [--intent-to-add | -N] [--refresh] [--ignore-errors]
|                [--ignore-missing] [--] [<filepattern>...]

I agree that it is potentially confusing, but the manpage references
are clearly recognisable as such.

Personally I don't consider it necessary to change this, since it's
clearly not horribly complicated to figure out the meaning, but here's
a patch for the sake of completeness.

Subject: [PATCH] Documentation/git.txt: explain that manpages for subcommands exist

On the off chance that it is not apparent that the manpages for
individual git commands explain how to use git commands (e.g. if
someone manages to conclude that "git git-add" is the way to use
git-add(1)), add a small explanation about that.
