This is the output
+ STATEMENT='cvs commit -m "This is" ../PBP/EIR.ENTRY'
+ echo cvs commit -m '"This' 'is"' ../PBP/EIR.ENTRY
cvs commit -m "This is" ../PBP/EIR.ENTRY
+ exit 0
Problem: Notice the single quotes between "This" and "is" ... This causes the called program "cvs" to think those are separate parameters which they are not.
If I change the shell to this
Then this is the ouput
Please do not pass this off as a "cvs" problem. It is not. If I change the script to this
Then this is the output
+ STATEMENT='cvs commit -m "Thisis" ../PBP/EIR.ENTRY'
+ echo cvs commit -m '"Thisis"' ../PBP/EIR.ENTRY
cvs commit -m "Thisis" ../PBP/EIR.ENTRY
+ cvs commit -m '"Thisis"' ../PBP/EIR.ENTRY
+ exit 0
How do I get bash to ignore that space?

bash does not parse quotes inside quotes or other forms of that sort of doublethink. To make it do so, you use eval.
The reason it doesn't parse quotes inside quotes and the like is the same reason eval tends to be avoided -- parsing syntax inside syntax leaves you open to someone injecting a `rm -Rf ~/` into your input and having your code execute that.
NOTE:
cvs = Concurrent Versions System
commit = commit to the cvs repository
-m = What follows in the quotes is the Log message for this revision
"This is" = the Log message for this revision
./q.sh = the file
This works:
What I want to be able to do is dynamically create that whole string in the script and execute it.
This fails
This fails
This is so frustrating because it seems so simple. I am feeling like a not so bright person right now.
