Re: two completion problems.

["Zvi Har'El" <rl@xxxxxxxxxxxxxxxxxxx>]

Looking again at the acroread problem, I noticed the parantheical remark at
_acroread, 

# Try extracting the version number directly from the executable.
# (This will fail if the executable is a wrapper script for acroread.)


I am using the AdobeReader_enu-7.0.9-1.i386.rpm from Adobe, and acroread IS a
shell script! However, just to what the version is, it is enough to run 
    
    acroread -version

I don't know about older version, but for my version the following patch will
do:

I haven't checked acroread version 6 or below.
