[PATCH] gitk: Do not hard-code "encoding" in attribute lookup functions

[PATCH] gitk: Do not hard-code "encoding" in attribute lookup functions

[Johannes Sixt]

From: Johannes Sixt <j6t@kdbg.org>

Commit 39ee47e (Clean up file encoding code and add enable/disable option,
2008-10-15) rewrote the attribute lookup functions gitattr and
cache_gitattr, but in the process hard-coded the attribute name "encoding"
instead of using the functions' parameters. This fixes it.

This is not a serious regression because currently all callers look only
for "encoding".

Further note that this fix assumes that future callers will not pass an
attribute name that contains regex special characters.
