Yes, that is less obfuscated version of that, whichever you feel more
comfortable with... for more discussion about the alternatives here see:

(but don't look that -- it is unnecessary and only causes headache ;D)

$ bash -c 'arg=${0//\\/\\\\}; echo ${arg//\"/\\\"}' 'this"is\a test'
this\"is\\a test
$ zsh -c 'arg=${0//\\/\\\\}; echo ${arg//\"/\\\"}' 'this"is\a test' 
this\"is\a test 
$ ksh -c 'arg=${0//\\/\\\\}; echo ${arg//\"/\\\"}' 'this"is\a test' 
this\"is\\a test

Interestigly zsh on Scientific Linux 6.2 fails here (zsh 4.3.10) -- I tried
various tricks and none helped. Hmm also zsh 4.3.17 on Ubuntu 12.04 fails.
zsh 5.0.2 on Fedora 20 works OK. ksh & bash installed on all these 3
systems work OK (and also bash 3.2.51... on Mac OS X). 

IMO this quoting should be done -- so I can send you email with:
