The bzip2 package includes wrappers around diff, grep and less/more.
These shell scripts currently include /usr/bin (and sometimes /bin) on
the PATH, and therefore fail if any of the commands that they rely on
cannot be found.
By substituting /usr/bin (and /bin) for the appropriate package paths,
these scripts work much more reliably.
I had some issues with bzmore which uses more from util-linux, I think
there might be a circular dependency in the Guix package tree, as I get
a VM stack overflow when including util-linux as a input to bzip2.
Note that as the bzip2 package is used by so many other packages, any
non-superficial change to it probably means rebuilding the world.
Below is a script, and two invocations of it, showing first what happens
with the unaltered package, and then the package with the modifications
I describe above.
