------------------------


The string_list() routine, which is used to parse strings into lists for many of
the qsub/qalter/et al utilities, does not complain about unmatched quotes.  For
example, the following is possible:

% qalter -ac "'bob" 737
modified context of job 737
% qstat -j 737 | grep context
context:                    'bob

and

% qalter -ac \"bob 738
modified context of job 738
% qstat -j 738 | grep context
context:                    "bob

This issue is in the same bit of code as Issue 1762 and Issue 1555.  Since this
issue has not yet proven to be a problem for a customer, I'm setting it as a P4.

Changed the affected platform.

In the case of an unmatched quote, the behavior is as though the matching quote
were placed at the end of the argument.  For example:

qsub -ac "test='1,2,3" -N \"bob sleeper.sh

will set the value of test to '1,2,3 and the name to "bob, but from a functional
perspective, that's ok.  Running:

qalter -dc test 123

will delete the full contents of test, as though the closing quote were present.
