Clean-up leaving files behind

[rpspringuel]

The new glog files are not removed by the clean-up mechanism.

It appears the *-preamble.tex are not removed for the gabc-output tests.

I don't think there is any clean-up going on in the scripted tests.

gabc and gtex files are not being cleaned up behind the tex-output tests.

There is no clean-up with the scripted tests as they don't have a defined behavior.

[henryso]

I don't think it's possible to clean up after the tex-output tests because there's no way to predict the names of the gabc files.

[henryso]

I added glog and preamble cleaning for gabc-output tests.

I have no solution yet for scripted and tex-output tests.

The nature of this problem has morphed since it's original creation, but there's still the possibility of improvements in this area. Looking at the test repository, the files still not cleaned up are:

• expectations that belong to another test type for soft-linked tests (i.e. gabc-dump tests don't clean up *-preamble.tex, *.exp and *.pdf files, gabc-gabc tests don't clean up *-preamble.tex, *.dump, and *.pdf files, and gab-output tests don't clean up *.dump and *.exp files in folders like glyphs which is softlinked into all three categories)
• scripted tests (they appear to produce *.out and *.log files and the test*.sh (and *.dat for kpsewhich also remains)
• scripted/recorder doesn't clean up (like other scripted tests), but produces significantly more files as there's a whole latexmk compilation scheme in this test, so I mention it separately
• tex-output and plain-tex tests don't remove *.gabc (though note above note about difficulty of predicting this file name) and tmp-gre folder
