Subject: gitk: Do not hard-code "encoding" in attribute lookup functions
X-Git-Url: http://privyetmir.co.uk/gitweb.cgi?a=commitdiff_plain;h=097e11182213afa4166c0fe58bd8135d71b52fb5;p=gitk

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

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.
