Moreover you can refer to the source tree 'at revision #NNNN', which I find
quite convenient for checkouts and tarball snapshots.

Perforce uses a similar incremented global revision number.

Perl 5 uses Perforce as its main source repository since 1997, and has reached
change #17914 -- including all changes in maintenance and architecture-specific
branches. Those numbers don't confuse people, and it's very useful to know,
for example, that change #NNNN introduced some bug, or that change #MMMM
corrected some other bug.
