Update GMT TM PostSCript

[PaulWessel]

For some reason did not fail test. @seisman why would the GMT_TM.sh test not fail when the orig had crooked annotations and the new one horizontal. Surely a large RMS. @meghanrjones even made the RMS smaller to see but still no fail?

[seisman]

gmt/test/gmtest.in

Lines 15 to 16 in acbef76

	# Is it a modern mode script?
	modern=$(grep "gmt begin" "$script" -c)

It's a modern mode script, but the variable modern is incorrectly given a 0 value.

gmt/test/gmtest.in

Lines 284 to 287 in acbef76

	# Modern mode needs to reestablish the $ps variable before exit
	if [ "X$script_mode" = "XM" ] && [ "X$ps" = "X" ]; then
	ps="${local_script%.sh}.ps"
	fi

Perhaps we should change these lines to:

 if [ "X$ps" = "X" ]; then 
 	ps="${local_script%.sh}.ps" 
 fi

If the variable is empty, we should assume that the PS file is the same as the script file.

Ah, yes, that is a good solution.

[seisman]

Ah, yes, that is a good solution.

It's unclear to me whether the solution will have a bad effect on those pass-fail tests.

[PaulWessel]

Hm, will need to look at the test script to see what a $ps variable does. I think it tries to see if the file exist before doing things. Anyway TGIF seminar in 2 minutes here....

[seisman]

I'll run the full tests and see how it works.

[PaulWessel]

Maybe @meghanrjones can look at the new failures and decide if it is mostly more of the same (update PS only).

Yes, will do.

Closing this one because GMT_TM is included in #4962
