I don't use -var-evaluate-expression for current GDB.

If I don't like Vladimir's patch on its own, I don't see why I should like it
with --all-values in -var-set-format.  But I'm probably missing your point.

What would "-var-set-format --all-values" return?  The value in the current
format or all formats?

When GDB stops I use "-var-update --all-values" to find out which watch
expressions have changed.  What are you proposing that I should use?
