Hi Pratyush,

A lot of places have unused global variables declared. Remove them.

It started as a couple of quick fixes and ended up in me writing an ugly
hacky script to catch all the instances of unused global declarations.
Lot more than I expected.

The script can be found at [0].

Wouldn't it make more sense to integrate that script into a Makefile
target `check`, rather than hiding it in a gist (that might become
unavailable if GitHub goes away, as some of you seem to fear)?

The script at [0] will only catch the unused globals in 'proc's. But
git-gui also has 'method's and 'constructor's. Just change '^proc' to
'^constructor' or '^method'.

Why not use `grep -E -n -e '^(proc|method)'`?

I manually checked each instance before removing just to be sure I'm not
doing something wrong. Still, a bit of testing would be appreciated.
Just apply this patch and go on about your business as usual. There
_should_ be no change in the behaviour. I tested some basic functions
like commit, push, etc, and they work fine for me.

I would, if I used Git GUI regularly ;-)

Ciao,
Dscho
