Perhaps --depth=0 should also work as if --tags were specified on
command line?  BTW. shouldn't git fetch tags that point to commits
that got doenloaded because of deepening the clone?

If there were more options that use <n> == 0 to actually mean unlimited
(infinity), perhaps it would be better to extend parseopt to provide for
such situation, e.g. OPT_INT_INF or something.  This way we would avoid
code duplication.

... oh, wait, the newly introduced[1] git-merge `--log-limit' option
uses --log-limit=0 to mean unlimited.
