[PATCH 0/7] Minor changes to 'list' command.

[Andrew Burgess]

The main motivation for this patch series was patch #6, this adds an
extra error when trying to use 'list -' to list off the beginning of a
file.

Patch #5 fixes a small inconsistency that I spotted while in the area,
and patches #1 to #4 are just clean up.

Patch #7 extends the command help for 'list'.
