fsck allows a name with > character in it like "name> <email>". Also for "name email>" fsck says "missing space before email". More precisely, it seeks for a first '<', checks that ' ' preceeds it. Then seeks to '<' or '>' and checks that it is the '>'. Missing space is reported if either '<' is not found or it's not preceeded with ' '. Change it to following. Seek to '<' or '>', check that it is '<' and is preceeded with ' '. Seek to '<' or '>' and check that it is '>'. So now "name> <email>" is rejected as "bad name". More strict name check is the only change in what is accepted. Report 'missing space' only if '<' is found and is not preceeded with a space.
