With cogito 0.18.1, cg-help line 152 invokes "IFS=$'\n' colorize", which
in turn invokes the "pager" shell function from cg-Xlib with IFS set to
just a newline. This means that if PAGER contains any spaces, the
expansion of ${PAGER:-less} within pager() will not be split, leading to
the following less-than-useful help message:
$ echo $PAGER
less -s
$ cg help
/usr/lib/cogito/cg-Xlib: line 193: less -s: command not found
$ echo $?
127
This patch fixes the problem:
