${vcs_info_msg_N_} (Note the trailing underscore)Where N is an integer, e.g., vcs_info_msg_0_. These variables
are the storage for the informational message the last vcs_info call
has assembled. These are strongly connected to the formats,
actionformats and nvcsformats styles described above. Those styles
are lists. The first member of that list gets expanded into
${vcs_info_msg_0_}, the second into ${vcs_info_msg_1_}
and the Nth into ${vcs_info_msg_N-1_}. (See the max-exports
style above.)
All variables named VCS_INFO_* are for internal use only.
