I have done some inspection, and came up with the following mostly cosmetic patch. I did not test the most important things (that the scripts work!), but I hope having the code in branch will be enough.
insert xfig figures (external or directly) failed for 1.4.3svn for some file extension issues (pstex vs pstex_t). I will have a look at it later.
I'll apply it soon. I guess some of it applies to trunk too.
Please also apply to the trunk. Bo
