The sort command in the FUSE runtime shell seems to cut/omit the first line of its output.

In this example, first I print a list of 4 features; then I pipe the output through the sort command; then I pipe it through sort again, this time using the -r flag to reverse the order.

smx@root:/> features/list | grep " cxf"
[uninstalled] [4.1.0.2-fuse] cxf-jaxrs
[installed ] [2.2.2.1-fuse] cxf
[uninstalled] [4.1.0.2-fuse] cxf-nmr
[uninstalled] [4.1.0.2-fuse] cxf-osgi

smx@root:/> features/list | grep " cxf" | sort
[uninstalled] [4.1.0.2-fuse] cxf-jaxrs
[uninstalled] [4.1.0.2-fuse] cxf-nmr
[uninstalled] [4.1.0.2-fuse] cxf-osgi

smx@root:/> features/list | grep " cxf" | sort -r
[uninstalled] [4.1.0.2-fuse] cxf-nmr
[uninstalled] [4.1.0.2-fuse] cxf-jaxrs
[installed ] [2.2.2.1-fuse] cxf

When I pipe the output through "sort", the first entry "cxf" is missing.

When I pipe the ouptut through "sort -r", the first entry "cxf-osgi" is missing.

I applied the same test to various command outputs (another simple example is "help features"), but always the behaviour is the same.
