git-completion.tcsh: fix redirect with noclobber

Ariel Faigon · gitster · commit 0b1f688bf453 · 2015-06-09T11:21:15.000-07:00
tcsh users who happen to have 'set noclobber' elsewhere in their
~/.tcshrc or ~/.cshrc startup files get a 'File exist' error, and
the tcsh completion file doesn't get generated/updated.

Adding a `!` in the redirect works correctly for both clobber (default)
and 'set noclobber' users.
