[PATCH] gitk: replace tabs with spaces (again)

[Denton Liu <liu.denton@xxxxxxxxx>]

In e244588eb6 (gitk: replace tabs with spaces, 2020-09-10), tabs were
replaced with spaces so that indents consistently use spaces. However,
in 6cd80496e9 (gitk: Resize panes correctly when reducing window size,
2020-10-03), some tabs were erroneously reintroduced.

Convert these tabs back into spaces.

This was done mechanically by running:

	$ expand -i gitk >gitk.new
	$ mv gitk.new gitk
	$ chmod +x gitk

This patch should be empty with `--ignore-all-space`.
