Yeah, except for the phrase "after the change" may give me a hiccup
or two while reading, because it is unclear if "the change" refers
to this patch (which is the intended interpretation) or the change
made in one of these two instances of gitk process.
Expressing the behaviour your patch modifies in the imperative mood,
as if you are ordering our codebase "to become like so", would avoid
such a hiccup, i.e./e.g.
Re-read the current on-disk configuration variables and
overwrite only the ones changed in this process when saving
the file, to preserve the changes made by other instances.
or something like that, perhaps?

Exactly.
