[PATCH] gitk: Display commit messages with word wrap

[Sergey Vlasov <vsu@altlinux.ru>]

Some people put very long strings into commit messages, which then
become invisible in gitk (word wrapping in the commit details window is
turned off, and there is no horizontal scroll bar).  Enabling word wrap
for just the commit message looks much better.
