Subject: net.c: Convert SS_IS_ADDR_V4MAPPED() to lower case.
X-Git-Url: https://git.tuebingen.mpg.de/?a=commitdiff_plain;h=5fd4a56660e000afbd2a193b869242d2e02de83e;p=paraslash.git

net.c: Convert SS_IS_ADDR_V4MAPPED() to lower case.

It's not a macro, after all. Remove the superfluous braces and fix
a whitespace issue while at it.
