How does man find git's subcommand manpages?
On my MacOSX machine, “man git log” only shows the manual page for git(1).
How does the linux man know that the two arguments “git” and “log” should be combined to find the “git-log” manpage? How would I get the same result in OSX?

This is a feature of the particular implementation of
man used on many Linux systems. Referring to the documentation (for
man), it is mentioned in the description of the
manwill try to interpret pairs of manual page
names given on the command line as equivalent to a single
manual page name containing a hyphen or an underscore. This
supports the common pattern of programs that implement a
number of subcommands, allowing them to provide manual pages
for each that can be accessed using similar syntax as would be
used to invoke the subcommands themselves.
Other implementations of
man can do different things. For instance (not well documented, but there if you study it), a quick check for
man git status on OSX El Capitan shows it tries to find a manual page for status. However,
man git-status gives a manual page.
