[PATCH] gitk: Remove mc parameter from proc show_error

[Alex Henrie <alexhenrie24@gmail.com>]

This partially reverts commit 8d849957d81fc0480a52570d66cc3c2a688ecb1b.

This change makes the string "OK" translatable and the string "mc" not
translatable. It will take effect the next time `make update-po` is run.
