Subject: gml2gv: silence a -Wimplicit-fallthrough warning
X-Git-Tag: 4.0.0~37^2

gml2gv: silence a -Wimplicit-fallthrough warning

All paths in this case end in a call to `exit`. But the compiler is apparently
unable to determine this, so use an explicit `break` to suppress a false
positive warning.
