Re: [PATCH: gdb/mi + doco] -var-update

[Nick Roberts <nickrob at snap dot net dot nz>]

I would like to commit this (source code) patch from last month. I accidently
reverted some of changes last time I presented it so I attach it here in its
proper form.

As Andrew doesn't appear to around is there any chance a global maintainer
can look at it? Its pretty lightweight.
