At least on my system, latex does not stop on errors. I created a bunch
of incorrect formulae among many correct ones. Latex gave simple list of
correct ones and long error messages/attempts-to-fix for incorrect ones.

My only worry about the process is that maybe some incorrect formulae
are bad enough to affect others. Say, latex may think these four
snippets cor,inc,cor,inc as cor,inc,inc and all the index will be wrong.
Whether latex stop on errors or not, it is a good idea to compare the
number of previews between latex and log file.

As long as it does not change across different flavor of latex, Preview:
Tightpage and Preview: Snippet are good anchors of previews.

I guess so. I was tempted to keep ${TEXFILE} and only replace DVI and
LOG with new ones as I did in the previous patch.

Yes. I was not so sure about Tightpage so I used 'non-Snippet'.

Under what condition will this line disappear? I thought that this line
will exist for both correct and incorrect first preview.

g: global. m: let ^ be beginning of line even when we deal with multiple
lines all at ones. s: let . match new line. c: continue (later with
different pattern.)

You can tell that English is not my native language everywhere. :-)
