Hello,
For some reason the authors of `makeinfo' thought it would be a good
idea to split the generated info file into two files by default once
its size reaches a certain undocumented threshold.
When that happened to me for the first time I was very surprised and
thought that "foo-1.info" and "foo-2.info" were some intermediate
files, added appropriate rules to ".gitignore", and went on shipping
an outdated "foo.info" for a while. (Off topic: I no longer ship
"*.info" files, just "*.texi".)
Since I have figured out what is going on, I am using this:
(setq org-texinfo-info-process '("makeinfo --no-split %f"))
Please consider making this the default value.
Best regards,
Jonas
