Subject: Fix constness of input in mozilla-sha1/sha1.c::SHA1_Update().
X-Git-Tag: v0.99.9b^2~10
X-Git-Url: https://git.verplant.org/?a=commitdiff_plain;h=77ab8798d3f8df39877235be17bb6e70077aaba2;p=git.git

Fix constness of input in mozilla-sha1/sha1.c::SHA1_Update().

Among the three of our own implementations, only this one lacked
"const" from the second argument.
