This config variable makes it possible to choose the default format
used to display help. This format will be used only if no option
like -a|--all|-i|--info|-m|--man|-w|--web is passed to "git-help".
The following values are possible for this variable:
- "man" --> "man" program is used
- "info" --> "info" program is used
- "web" --> "git-browse-help" is used
By default we still show help using "man".
This patch also adds -m|--man command line option to use "man"
to allow overriding the "help.format" configuration variable.
Note that this patch also revert some recent changes in
"git-browse-help" because they prevented to look for config
variables in the global configuration file.

The users used to be able to say "git help cat-file" from anywhere, but
the browse-help script insisted to be in a git repository, which caused
"git help -w cat-file" to barf outside. Correct it.
While at it, remove leftover debugging "echo".

Now "git-instaweb" will try to use the browser configured as
"web.browser", if "instaweb.browser" is not set.
"git-browse-help" will check first "help.browser" and then
"web.browser".

Now when using "git help -w cmd", we will try to show the HTML man
page "git-cmd.html" in your prefered web browser.
To do that "help.c" code will call a new shell script
"git-browse-help".
This currently works only if the HTML versions of the man page
have been installed in $(htmldir) (typically "/usr/share/doc/git-doc"),
so new target to do that is added to "Documentation/Makefile".
The browser to use can be configured using the "web.browser"
config variable.
We try to open a new tab in an existing web browser, if possible.
The code in "git-browse-help" is heavily stolen from "git-mergetool"
by Theodore Y. Ts'o. Thanks.
