Simple fix for base64 decoding return's (deleted)

Description James Antill 2006-08-30 01:18:35 UTC
Description of problem:
 base64 -d doesn't accept returns (which the base64 encoding should put every 76
characters and at the end of the encoding).

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. echo x | base64 | base64 -d
2. perl -le 'print "a" x 80' | base64 | base64 -d

Additional info:
 base64 -id does work but (IMNSHO) the output of base64 and what the rfc says
you should do should hardly be clasified as garbage. However this does present
the obvious fix of looking for '\n' (and skipping it) on the else clause of the
ignore_garbage check.

Simple fix for base64 decoding return's

 This is a simple fix, although not very efficient and allows some things
through that shouldn't be allowed without -i. On the other hand it's so simple
it's obviously OK to apply.

I've fixed this properly for the next upstream coreutils release:
