[PATCH] init-db: Store current value of autocrlf

[Steffen Prohaska <prohaska@zib.de>]

Storing the current value of autocrlf to preserve it for this repository
even if the global setup changes is a good idea.  Changing autocrlf
later is tricky because the work tree's line endings depend on the
settings during checkout.  Therefore, it makes sense to preserve the
value of autocrlf that exists during the first checkout.  In this
regards autocrlf is different from, for example, author, because author
can be easily changed later without requiring any conversion of existing
files in the work tree.

This commit modifies the initialization of a new repository to store the
current value of autocrlf.
