Subject: [PATCH v2 01/10] rerere: unify error messages when read_cache fails

From: Thomas Gummerer <[email-masked]>
Date: Tue, 5 Jun 2018 22:52:10 +0100

We have multiple different variants of the error message we show to
the user if 'read_cache' fails.  The "Could not read index" variant we
are using in 'rerere.c' is currently not used anywhere in translated
form.

As a subsequent commit will mark all output that comes from 'rerere.c'
for translation, make the life of the translators a little bit easier
by using a string that is used elsewhere, and marked for translation
there, and thus most likely already translated.

"index file corrupt" seems to be the most common error message we show
when 'read_cache' fails, so use that here as well.
