Subject: base91: Patch the C version for our charset change
X-Git-Tag: v0.6.0~201
X-Git-Url: http://www.chiark.greenend.org.uk/ucgi/~ian/git?a=commitdiff_plain;h=d31e77241cb84539fa203ce41d739ed2841bfbff;p=secnet.git

base91: Patch the C version for our charset change

The base91.c.patch file was made by editing base91.c by hand and
running git diff.  The change to enctab is the obvious one.
The change to dectab was simply done by hand based on inspection.
