Setiathome startup script

[Jeff Walters]

I grabbed your email addresses from messages having to do with the latest 
setiathome commit and maintainer and wasn't sure who best to contact.

I am still having a slight problem with the setiathome.sh startup script.  It 
tells me setiathome is already running when it isn't.  After doing some 
messing around manually with "ps axo command | egrep 
/usr/local/libexec/setiathome.bin" on the command line, I found that 
intermittently the egrep command itself appears in the ps output and causes a 
match, which apparently causes the problem.

Perhaps the ps output lines beginning with "egrep" can be removed with a 
pipeline like below?

if ps axo command | egrep -v ^egrep | egrep ${wrapper_path}; then

instead of 

if ps axo command | egrep ${wrapper_path}; then

Thanks,
Jeff Walters
