git-p4: test cloning with two dirs, clarify doc

Browse Source 
Document how git-p4 currently works when specifying multiple
depot paths:

1.  No branches or directories are named.

2.  Conflicting files are silently ignored---the last change
    wins.

2.  Option --destination is required, else the last path is construed
    to be a directory.

3.  Revision specifiers must be the same on all paths for them to
    take effect.

Test this behavior.

@ -276,8 +276,15 @@ p4 revision specifier on the end:
"//depot/my/project@1,6"::
Import only changes 1 through 6.
"//depot/proj1 //depot/proj2@all"::
Import all changes from both named depot paths.
"//depot/proj1@all //depot/proj2@all"::
Import all changes from both named depot paths into a single
repository. Only files below these directories are included.
There is not a subdirectory in git for each "proj1" and "proj2".
You must use the '--destination' option when specifying more
than one depot path. The revision specifier must be specified
identically on each depot path. If there are files in the
depot paths with the same name, the path with the most recently
updated version of the file is the one that appears in git.
See 'p4 help revisions' for the full syntax of p4 revision specifiers.
