The command line is
        libtool --mode=execute myprog arg1 '' arg3

where the second argument to myprog is an explicit null string.
But libtool hangs ['sed' reading stdin] during the check for whether
the null string argument is the name of a library that libtool
must change to reflect uninstalled status or not.  The null
argument is the business of myprog.

In general, any "$file" containing shell metacharacters will cause
trouble because
        sed -e 4q  $file  |  ...
forgot to quote   "$file" .
