Re: [PATCH] mergetool: Replace use of "echo -n" with printf(3) to be more portable

The subject should probably refer to printf(1) instead of printf(3).

Here is one space too much after printf.

-	echo -n "'$path' is a symlink containing '"
+	printf "'$path' is a symlink containing '"

You should use printf "'%s' [..]" "$path" as you do in some other
places (in case $path contains conversion specifiers).

-    echo -n "Hit return to start merge resolution tool ($merge_tool): "
+    printf "Hit return to start merge resolution tool ($merge_tool): "

Here it is much more unlikely that $merge_tool contains a conversion
specifier but anyway I'd prefer to use %s.
