I've seen half a dozen in the past month.  (my fault, it was
problems in @example vs. @verbatim).

Are you sure?  I'd expect it to tolerate 1000 *warnings* before
terminating.  Warnings are not errors.

hmm, as far as I can see, texi2pdf doesn't have any --error-limit
flag, but makeinfo does.

$ man makeinfo
...
   General options:
       --error-limit=NUM
              quit after NUM errors (default 100)

WTF?!  David: is this seriously giving a zero return value if
there's any "errors" ?  Or does it still return a zero, but print
out multiple errors?

Easy way to make it fail immediately: add

@example
@\
@end example

to some file.  I recommend something in the CG.

makeinfo will not fail, but texi2pdf will fail.


What do you see if you set --error-limit=0 for makeinfo?  I'm
wondering if this is why we sometimes see "make" compiling the
docs but "make doc" failing.  If we can get "make" to be stricter
about checking the texinfo, this could save a lot of time in
writing docs.

If it would take less than 10 hours to fix the english docs, I
think we should set --error-limit=0.  We can leave it at 100 for
the translations for the next X months.

Wow, this is a really good find.
