[PATCH] gitk: Fix typo in proc blobdiffmaybeseehere

The recent 5de460a2 (Refactor per-line part of getblobdiffline and its support) introduced blobdiffmaybeseehere, and accidentally forgot the '$' to access the parameter as a TCL variable. This resulted in a failing "Back" button with the error

can't use non-numeric string as operand of "!"
    while executing
"if {!$ateof} {
	set nlines [expr {[winfo height $ctext]
			  / [font metrics textfont -linespace]}]
	if {[$ctext compare "$target_scrollpos + $nlines ..."
    (procedure "maybe_scroll_ctext" line 5)

It turns out to be just a simple typo.
