If your target is GTAGSLIBPATH, how about a more direct approach which
does not require dummy project such as:

[libsearch]
-------------------------------------------------------------------
#!/bin/sh
for d in `echo "$GTAGSLIBPATH" | sed -e 's/^:/.:/' -e 's/:$/:./' \
        -e 's/::/:.:/' -e 's/:/ /g'`
do
        (cd $d && global -a "$@")
done
-------------------------------------------------------------------

That word was missing. I will fix it.
Thank you!
