tsort bug

[Fang Zhe]

Hi,

First I want to say thank you for your great work on textutils. They are
all excellent software and very useful.

I guess I find a bug on tsort. When I call tsort with attached text file,
it result in memory fault and following output.

pws/dmlpws/tpi
tsort: text: input contains a loop:

tsort: cae/converter/src/common
tsort: cae/converter/src/utils
Memory fault
-------------------------------------------------------------------

I hope this information will be useful for you to improve the software.
And I'd like to ask for a latest version from you when you fix this bug.

Best Regards,
