Err, no. I doubt my ~/opt/noarch/.../...; ~/opt/`uname -i`/git/; etc.,
are pre-registered by my Linux distro or OS X 10.[45].

man man:
       If you specify the -M pathlist option, pathlist  is  a  colon-separated
       list of the directories that man searches.

       If  you  don’t specify -M but set the MANPATH environment variable, the
       value of that  variable  is  the  list  of  the  directories  that  man
       searches.

       If  you  don’t  specify  an  explicit path list with -M or MANPATH, man
       develops its own path list based on the contents of  the  configuration
       file /etc/man.config.  The MANPATH statements in the configuration file
       identify particular directories to include in the search path.
...
       In addition, for each directory in the command search path (we’ll  call
       it  a  "command  directory")  for  which  you do not have a MANPATH_MAP
       statement, man automatically looks for a manual page directory "nearby"
       namely as a subdirectory in the command directory itself or in the par-
       ent directory of the command directory.

So, according to the last paragraph, and assuming no -M argument and no
MANPATH environment variable are defined, man should be able to find the
manual pages for git commands if they're in PATH.
