Users may want to be able to read Git documentation, even if they are not command line users. There are many important concepts and terms covered within the standard Git documentation which would be useful to even non command line using people. We now try to offer an 'Online Documentation' menu option within the Help menu. First we try to guess to see what browser the user has setup. We default to instaweb.browser, if set, as this is probably accurate for the user's configuration. If not then we try to guess based on the operating system and the available browsers for each. We prefer documentation which is installed parallel to Git's own executables, e.g. `git --exec-path`/../Documentation/index.html, as that is how I typically install the HTML docs. If those are not found then we open the documentation published on kernel.org. Signed-off-by: NShawn O. Pearce <spearce@spearce.org>
